In figure, a particle is placed at the highest point A of a smooth sphere of radius r. It is given slight push, and it leaves the sphere at B, at a depth h vertically below A. The value of h is

A horizontal plane supports a fixed vertical cylinder of radius R and a particle is attached to the cylinder by a horizontal thread AB as shown in Fig. The particle initially rest on a horizontal plane. A horizontal velocity v_(0) is imparted to the particle, normal to the threading during subsequent motion. Point out the false statements:

A cylinder of radius R = 1 m and height H = 3 m two- thirds filled with water, is rotated about its vertical axis as shown in Fig. Determine the speed of rotation when a. the: water just starts spilling over the rim. b. the point at the centre of the base is just exposed.

A particle of mass m moves along the internal smooth surface of a vertical cylinder of the radius R. Find the force with which the particle acts on the cylinder wall if at the initial moment of time its velocity equals v_(0) . And forms an angle alpha with the horizontal.
