Task id16506
At point 1, located at a distance l1 = 1.4 m from the surface of a ball of radius r = 20 cm, having a surface charge density s = 30 μC/m2, there is a point charge q = 2 μC (Fig.). Find the work done when this charge is transferred to point 2, located at a distance l2 = 40 cm from the center of the ball.
