Question
1. Two small plastic spheres are given positive electrical charges. When they are 15.0 cm apart, the repulsion force between them has a magnitude 0.220 N. What is the charge on each sphere? (a) If the two charges are equal and (b) if one sphere has four times the charge of the other? 2. Two charges, one of 2.50 µC (at the origin) and the other of -3.5 µC, are placed on the x-axis, one at the origin and the other at x=0.600 meters. Find the position on the x-axis where the net force on a small charge +q would be zero. = q2 = 2.0 µC are located at x = 0, y = 0.30 3. Two equal positive point charges q1 and x =0, y = -0.3 m, respectively. What are the magnitude and direction of the total (net) electric force that these charges exert on a third point charge Q = 4.0 µC at x= 0.40, y =0?
