A ball is moving to and fro about the lowest point A of a smooth hemispherical bowl. If it is able to rise up to a height of 20 cm on either side of A , its speed at A must be (Take `= 10m//s`, mass of the body 5 g )

A smooth steel ball is moving to and fro about the lowest position of a frictionless hemispherical bowl. The ball attains a maximum height of 20 cm on either side of O. If g = 10 ms-2, and mass of the body is 5g, the speed of the ball when it passes through O will be:

A ball of mass m is pushed down the wall of hemispherical bowl from point A. It just rises up to edge Q of the bowl. Find the speed at which ball is pushed down.
