A charge Q is uniformly distributed inside a non- conducting sphere of radius R . Find the electric potential energy stored in the system.

A system consists of two small spheres of masses m_1 and m_2 interconnected by a weightless spring. At the moment t=0 the spheres are set in motion with the initial velocities v_1 and v_2 after which the system starts moving in the Earth's uniform gravitational field. Neglecting the air drag, find the time dependence of the total momentum of this system in the process of motion and of the radius vector of its centre of inertia relative to the initial position of the centre.
