A picture can be hung in four different ways using wires of equal lengths. In which orientation will the tension in the wires be maximum?
- A
- B
- C
- D
Correct Answer

A. D

Explanation

When a picture is hung using wires of equal lengths, the tension in the wires will be maximum when the picture is hung in orientation D. This is because in orientation D, the weight of the picture is distributed equally among all four wires, resulting in the maximum tension in each wire. In the other orientations, the weight of the picture is not distributed equally among the wires, leading to lower tension in some of the wires.

A stationary object of mass 2.0 kg is suspended using two strings as shown below. What is the resultant force acting on the object?
- 0 N
- 8 N
- 20 N
- 48 N
Correct Answer

A. 0 N

Explanation

Key word here is suspended, hence not moving.

A horizontal force of 80 N is needed to pull a sled forward. If the rope pulling the sled makes an angle of 30^o with the horizontal, what is the tension in the rope?
- 40 N
- 69 N
- 92 N
- 160 N
Correct Answer

A. 92 N

Explanation

When the rope makes an angle of 30 degrees with the horizontal, the tension in the rope can be calculated using the formula Tension = Force / Cosine(angle). In this case, the force is 80 N and the angle is 30 degrees. Plugging these values into the formula, we get Tension = 80 N / Cos(30 degrees) = 92 N. Therefore, the tension in the rope is 92 N.

A 4.0 kg flower pot is having a circumference of 50 cm is suspended by three ropes of equal lengths from the ceiling. The ropes make an angle of 60^o with the horizontal plane. Determine the tension in one of the ropes.
- 13.3 N
- 15.4 N
- 23.1 N
- 26.7 N
Correct Answer

A. 15.4 N

Explanation

Treat the 3 ropes to be inclined to the vertical and make them equate to the weight of the flower pot.
