A `10kg` ball attached at the end of a rigid massless rod of lengh `1m` rotates at constant speed in a horizontal circle of radius `0.5m` and period of `1.58s` , as shown in the figure. The force exerted by the rod on the ball is `(g=10ms^(-2))`

A liquid of mass 1 kg is filled in a flask as shown in figure. The force exerted by the flask on the liquid is (g=10m//s^(2)) [Neglect atmospheric pressure]:

A ball of mass 10 gm dropped from a height of 5m hits the floor and rebounds to a height of 1.25m. If the ball is in contact with the ground for 0.1s, the force exerted by the ground on the ball is (g=10 m//s^(2))

A particle is attached to an end of a rigid rod. The other end of the rod is hunged and the rod rotates always remaining horizontal. Its angular speed is increasing at contant rate. The mass of the particle is m . The force exerted by the rod on the particle is vecF , then:
