A small body of mass m slides down from the top of a hemisphere of radius r . The surface of block and hemisphere are frictionless. The height at which the body lose contact with the surface of the sphere is

A small block slides down from the top of hemisphere of radius R = 3 m as shown in the figure. The height 'h' at which the block will lose contact with the surface of the sphere is __________ m. (Assume there is no friction between the block and the hemisphere)

Total surface area of a hemisphere of radius r is :

The curved surface area of a hemisphere of radius r is :

A small body of mass m slides down from the top of a frictionless hemispherical surface of radius r as shown in the figure.The vertical height h below the highest point at which the body gets separated from the hemispherical surface. .

A small body of mass m slides without friction from the top of a hemisphere of radius r. At what hight will the body be detached from the centre of hemisphere?

A small body of mass m slides without friction from the top of a hemisphere of radius r. At what hight will the body be detached from the surface of hemisphere?

A small spherical ball of mass m slides without friction from the top of a hemisphere of radius R.At what height will the ball lose contact with surface of the sphere?

The total surface area of a solid hemisphere of radius r is

A small body of mass m slide without friction from the top of a hemispherical cup of radius r as shown in figure. If leaves the surface to the cup at vertial distance h below the highest point then

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.
