Problem 30823.
The figure shows a charged thread MN (tau1 = 0.2 nC/cm) and a cylinder (tau 2 = - 0.1 nC/cm); a = 20 cm. Find: forces acting on a particle whose charge (q = 0.1 nC, at points A and C from the electric field; change in the potential energy of a particle in an electric field when moving it from point A to point C.
