Twо pоint chаrges Q 1 = 2 . 50   μ C , Q 2 = 2 . 50   μ C   lie аlоng а circle of radius r = 50 . 0   c m  at angles of 30 . 0 ° , 150 . ° , as shown in Fig. 1. (a) What are the magnitude and direction of the net electric field at the center of the circle? If a third point charge Q 3 is placed on the upper half part of the circle so that the electric field at the center of the circle is zero, (b) what location should Q 3 be placed and what is Q 3 ? (c) What is the electric energy of the three-charge system? If a point charge q = - 3 . 00   μ C is moved from the center of the circle to point A in Fig. 1, (d) what is the work done by electric force on q ? (e) If q is moved from the center of the circle to infinity, what is the work done by the electric force on q ? t1_fig_q11_09282025.jpg
