A point charge q1 = +3.80 μC is at origin. How far should the second point charge of +6.20 μC be placed to have electric potential energy of 0.700 J?
Two charges lie on positive x-axis . Charge A (3.0 x 10-10 C) is 3.0 cm from the origin and Charge B is 5.0 cm from the origin (-4.0 x 10-10 C). What is the total force exerted by these two charges on charge C (6.0 x 10-10 C ) located at the origin ?
What is the resistance and temperature coefficient of resistance of a resistor if its color code is yellow-green-blue-violet-red-yellow?
