. Inside a smooth hemispherical cavity a particle P can slide freely.


Inside a smooth hemispherical cavity a particle P can slide freely. The block having this cavity is moving under constant acceleration A = g m/s2. A particle is released from the state of rest from the position shown. The angle q with the vertical, when the particle will have maximum velocity with respect to the block is

 

Best Answer

Velocity will be maximum w.r.t. block when net force w.r.t. block will become perpendicular  to the relative velocity. From FBD of the particle w.r.t. the cavity
