A solid sphere and sphere and a hollow sphere of same mass M and same radius R are released from the top of a roug inclined plane. Friction coefficient is same for both the bodies. If both bodies perform imperfect imperfect rolling, the
Statement I : Maximum value of friction force between two surface is `mu xx` normal reaction. where `mu` coefficient of friction between surface.
Statement II : Friction force between surface of a body is always less than or equal to externally applicent force.

Answer

C

Explanation

Statement-2 is false because friction force may be more than applied force when body is retarding and external force is acting on body.
