2. In the diagram shown the shaded block is fixed. The mass of block A is 4 kg and the coefficient of friction between the shaded block and block A is 1/4. What should be the maximum weight of the block b so that the whole system remains in the state of equilibrium?

Explanation

Submit
3. During the motion of the bicycle, a force of friction is exerted by the ground on the two wheels of the bicycle. Which of the following statement is true in this context?

Explanation

The frictional force exerted by the ground on the two wheels of the bicycle depends on the surface and the weight of the bicycle and the person sitting on it. The type of surface and the weight of the bicycle and the person affect the amount of friction between the wheels and the ground. The frictional force does not depend on the motion of the wheels or act in the direction of the motion.

4. A passenger is traveling in a train moving at a speed of 50 m/s. Briefcase of the man is resting on the berth of the train. Suddenly the driver applies brakes due to which the speed of the train decreases at a speed of 15 m/s in 3 s. What should be the minimum coefficient of friction between the berth and the briefcase so that the briefcase doesn't slide down? (take g = 10 m/s2)

Explanation

Submit
5. An ant is slowly crawling up a hemispherical surface with negligible speed. The coefficient of friction between the ant and the surface is 2/3. If the line joining the ant and the center of the hemispherical surface subtends an angle 'θ' with vertical, then which of the following is true?

Explanation

Submit
6. In the diagram weight of A = 250 N, the weight of B = 150 N, the weight of C = 100 N. The value of the coefficient of friction between A & B is 0.7 and that is between B & C is 0.4 and between C and the ground, the coefficient of friction is 0.3. What should be the minimum value of force F so that any part of the system shown in the figure starts moving?

Explanation

Submit
7. Which of the following statement is wrong about the friction?

Explanation

Comparison of two physical quantities is not done on the basis of the direction of the quantities.

Submit
8. A block of mass 0.2 kg is held against a wall by applying a horizontal force of 6 N on the block. If the coefficient of friction between the block and the wall is 0.3, then what will be the value of frictional force acting on the block?

Explanation

Submit
9. two blocks A and B of different masses have velocities VA and VB respectively. A horizontal force F is acting on the block A. Coefficient of friction between A & B is μ and that of between B & ground is zero. If VA = VB then which among the following statement is correct?

Explanation

Submit
10. A particle starts from point C with some initial velocity in the hemispherical vessel of radius 'R'.
