Find the minimum height of the obstacle so, that the sphere can stay in equilibrium.

What is the position of centre of mass of a uniform sphere?

A hollow spherre is released from rest on a rough inclined plane as shown in the figure. Find the velocity of point of contact as a function of time. ( m = mass of hollow sphere, R = radius of sphere )

A block having equilateral triangular cross-section of side a and mass m is placed on a rough inclined surface, so that it remains in equilibrium as shown in figure. The torque of normal force acting on the block about its centre of mass is
