5. A thin ring of radius R = 10 cm carries a uniformly distributed charge Q = 0,1 SCLC. On the perpendicular to the plane of the ring, vosstavlennom of its middle, is the point charge Q1 = 10 nC. Determine the force F, acting on the point charge Q charged by the ring when it is removed from the center of the ring by 1) l1 = 20 cm; 2) l2 = 2 m.
