A block m is kept stationary on the surface of an accelerating cage as shown in figure. At the given instant, study the following statements regarding the block.

Question Image

(i) Normal reaction performs positive work on the block.
(ii) Work done by the friction force on the block is negative.
(iii) No net work is done by normal reaction and frictional force on the block.

A small body is placed on the top of a smooth sphere of radius R initially at rest. Then the sphere is imparted a constant acceleration a=g2 in the horizontal direction and the body begins sliding down. If the angle is θ0 between the vertical and the radius vector drawn from the centre of the sphere to the break-off point, calculate cosθ0 (Best approximation)
