Задача id12431

In a thin-walled non-conducting uniformly charged sphere with mass m1=5•10-5 kg and radius R=10-2 m there are two small diametrically opposite holes. Sphere charge q1=10-8 C. Initially the sphere is at rest. Along a straight line connecting the holes, a particle of mass m2=10-5 kg with a charge q2=3• 10-9 C, the same as q1, moves from infinity at a speed v=5 m/s. What will be the velocities of the bodies after they move away relative to each other to infinity?
