A small ball is released from rest from point A as shown. if bowl is smotth, than ball will exert more pressure at point B, compared to the situation if bowl is rough.
Reason: Linear velocity and hence, centripetal force in smooth situation is more.

A small ball of mass m is released from rest from the position shown . All contact surface are smooth . The speed of the ball when it reaches its lowest position is
