In the system shown in figure, mass m is released from rest from position A. Suppose potential energy of m at point A with respect to point B is E. Dimensions of m negligible and all surfaces are smooth. When mass reaches at point B.

A block of mass m is released from rest ffrom point A which rests on a semi circular groove as shown in the diagram. Find value of normal reaction between the vertical wall and the large block of mass M when m reaches at B.

Two blocks A and B of masses 10 kg and 5 kg respectively are placed inside a cart which is moving horizontally with an acceleration of 2 m/s^2 as shown in the figure. If all the surfaces are smooth then the ratio of normal reaction between the block A and vertical surface of the cart and normal reaction between the blocks A and B is

In the figure shown A and B are free to move . All the surface are smooth. Mass of A is m . Then

In the figure shown A and B are free to move . All the surface are smooth. Mass of A is m . Then
