A particle rests on the top of the hemisphere of radius
R. The small horizontal velocity that must be imparted
to the particle if it is to leave the hemisphere without
sliding down. is-

Answer 1

A particle rests on the top of a smooth hemisphere of radius r. It is imparted a horizontal velocity of √ηgr. Find the angle made by the radius vector joining the particle with the vertical at the instant the particle losses contact with the sphere.

The smallest horizontal velocity v2 = gR where R is the radius of hemisphere v = √(gR)
