In the adjacent figure there is a cube having a smooth groove at an inclination of \( 30^{\circ} \) with horizontal in its vertical face. A cylinder \( A \) of mass \( 2 kg \) 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 \( g \sqrt{3} \) (C) The value of \( a_{0} \) is \( g \). (D) Acceleration of the particle in ground frameFigure 2.192 is \( g \) |
