Electric and Magnetic Fields Assignment 1. Three small balls are charged and placed at the vertices of an equilateral triangle ABC the side length of which is 2.0 m. The charges of the balls are qA = 2.0 uC,q3 = 2.0 uC, and qc = 1.0 uC. a. Find the net force acting on the charge qc. Sketch a diagram.(4A, 2C) b. Find the electric potential energy of the system of charges. (3A) c. Find the electric field and electric potential at the midpoint of the side AB. (6A) 2. The distance between two point charges, q1 = 1.5 pi? and q2 = 2.5 uC, equals 0.50 m. What work has to be done in order to bring together the charges up to a distance of 0.25 m? (2T) 3. Electrons leave the cathode of an electron device and move to the anode. The electric potential difference between the cathode and anode is 2.0>
