In the adjacent figure there is a cube having a smooth groove at an inclination of `30°` with horizontal in its vertical face. A cylinder A of mass 2kg can slide freely inside the grove. The cube is moving with constant horizontal acceleration `A_(0)` parallel to the shown face, so that the slider does not have acceleration along horizontal.

A

The normal reaction acting on cube is zero

B

The value of `a_(0)` is `gsqrt(3)`

C

The value of `a_(0)` is g.

D

Acceleration of the particle in groimd frame is g

In the adjacent figure, a uniform cube of mass m and edge l=2m is lying at rest an a rough horizontal surface. A small ball of mass m hits the cbe at its top edge with horizontal speed v_(0) and sticks to it. Friction is so large that the cube can rotate about the edge 'O' without sliding. Calculate the minimum value of v_(0) ( in m/s) so that the cube will topple. Ignore any loss of energy due to friction at the edge O and take sqrt(2)-1=0.4 .
