A block of mass m slides down on inclined wedge of same mass m as shown in figure . Friction is absent everywhere . Acceleration of centre of mass of the block and wedge is

A

does not move

B

moves horizontally with constant speed

C

moves horizontally with increasing speed

D

moves vertically with increasing speed

Text Solution

Verified by Experts

The correct Answer is:
D

There is no external force on the block + wedge system, So, centre of mass doesn’t move in horizontal.
