A particle of mass `m` is released from the top of a smooth hemisphere of radius `R` with the horizontal speed `mu`. Calculate the angle with verticle where it loses contact with the hemisphere.

A particle is released from the top of a smooth hemisphere.find the angle rotated by the radius through the particle, when it loses contract with the hemisphere. Also sketch variation of normal contact force with cos theta , where theta is an angle rotated by the radius through the particle.

A block of mass as shown is released from rest from top of a fixed smooth hemisphere. Find angle made by this particle with vertical at the instant when it looses contact with hemisphere.

A particle is released from the top of the smooth hemisphere R as shown. the normal contact between the particle and the hemisphere in position theta is
