Answer both questions, multiple choice
Two positive charges Q1 and Q2 are placed 10 cm apart along the x-axis. Q1 is at the origin with a value equal to 5 mu C and Q3 = 7 mu C. A test charge Qo = - 3 mu C is placed at 3.7 cm from Q1. The Electrostatic Potential Difference between point A and B is A small sphere of mass 5.1 g hangs vertically from an insulating thread. A horizontal electric...
