### What quantity is gravitational force ?

• A.

Scalar quantity

• B.

Vector quantity

• C.

A and B both

• D.

None

B. Vector quantity
Explanation
Gravitational force is a vector quantity because it has both magnitude and direction. The magnitude of gravitational force is determined by the masses of the objects involved, and the direction is always towards the center of mass of the objects. This means that gravitational force can be represented by an arrow, indicating both the strength and direction of the force. Therefore, the correct answer is "Vector quantity".

### Which one of the following is true ?

• A.

Gravitational force is indirectly proportional to masses of two objects

• B.

Gravitational force is directly proportional to square of distance between two bodies

• C.

Gravitational force is directly proportional to masses of two bodies

• D.

None

• E.

A , b , c all

C. Gravitational force is directly proportional to masses of two bodies
Explanation
The correct answer is that gravitational force is directly proportional to the masses of two bodies. This means that as the masses of the two objects increase, the gravitational force between them also increases. The greater the mass, the stronger the gravitational force.

### Unit of G is ?

• A.

N m2 kg2

• B.

N m/kg

• C.

N m2 / kg2

• D.

N kg2/m2

C. N m2 / kg2
Explanation
The unit of G is N m2 / kg2 because G represents the gravitational constant, which is a physical constant that is used to calculate the force of gravity between two objects. The unit N represents Newton, which is the unit of force. The unit m2 represents square meters, which is the unit of area. The unit kg2 represents kilograms squared, which is the unit of mass squared. Therefore, the correct unit for G is N m2 / kg2.

### Gravitational acceleration does not depend on ?

• A.

Mass of the object

• B.

Weight of the object

• C.

Gravitation constant

• D.

Distance from earth surface

A. Mass of the object
Explanation
Gravitational acceleration does not depend on the mass of the object. This is because gravitational acceleration is a constant value for a given location and is independent of the mass of the object experiencing the gravitational force. The force of gravity experienced by an object depends on its mass, but the acceleration due to gravity remains the same. This means that objects of different masses will fall at the same rate in a vacuum near the Earth's surface.

### Where is the value of Gravitational acceleration is minimum ?

• A.

Alps - Europe

• B.

Equator

• C.

Poles

• D.

Tropic of cancer

• E.

Tropic of capricorn

B. Equator
Explanation
The value of gravitational acceleration is minimum at the Equator. This is because the Earth is not a perfect sphere, but rather an oblate spheroid, with the equatorial diameter being larger than the polar diameter. As a result, the centrifugal force due to the Earth's rotation is greater at the equator, counteracting some of the gravitational force. Therefore, the net gravitational acceleration is slightly lower at the equator compared to the poles or other latitudes.

### What is the value of Gravitational acceleration on the surface of the moon ?

• A.

9.8 m/s2

• B.

33 cm/s2

• C.

1.608 m/s2

• D.

15 m/s2

C. 1.608 m/s2
Explanation
The value of gravitational acceleration on the surface of the moon is 1.608 m/s2. This value is significantly lower than the gravitational acceleration on Earth, which is 9.8 m/s2. The moon has less mass than Earth, so its gravitational pull is weaker. This means that objects on the moon weigh less and fall more slowly compared to Earth.

### What will be the mass of the object on moon surface whose mass is 60 kg on earths surface

• A.

60 kg

• B.

10 kg

• C.

60 N

• D.

10 N

A. 60 kg
Explanation
The mass of an object remains the same regardless of its location. Therefore, if the mass of the object is 60 kg on Earth's surface, it will still be 60 kg on the moon's surface. The force acting on the object may change due to the difference in gravitational pull, but the mass itself remains constant.

### What is the unit gravitational force ?

• A.

Newton

• B.

Kelvin

• C.

Kg

• D.

Metre

A. Newton
Explanation
The unit gravitational force is measured in Newtons. Newton is the standard unit of force in the International System of Units (SI). It is named after Sir Isaac Newton, who formulated the laws of motion and universal gravitation. The unit represents the force required to accelerate a one-kilogram mass by one meter per second squared. Therefore, Newton is the appropriate unit for measuring gravitational force, as it quantifies the force exerted by gravity on an object.

### What is the weight of an object  on earths surfacewhich weighs 60 N on moon's surface ?

• A.

360 N

• B.

10 N

• C.

60 kg

• D.

2 kg

A. 360 N
Explanation
The weight of an object on Earth's surface is greater than its weight on the moon's surface due to the difference in gravitational force between the two celestial bodies. Since the object weighs 60 N on the moon, it must weigh more on Earth. Therefore, the correct answer is 360 N.

### Weight depends on which two factors ?

• A.

Mass and energy

• B.

Mass and gravitation constant

• C.

Mass and Gravitational acceleration

• D.

Above a, b,c

• E.

None

C. Mass and Gravitational acceleration
Explanation
The weight of an object depends on two factors: mass and gravitational acceleration. Mass refers to the amount of matter in an object, while gravitational acceleration refers to the acceleration due to gravity. The weight of an object is calculated by multiplying its mass by the gravitational acceleration. Therefore, both mass and gravitational acceleration play a crucial role in determining the weight of an object.
