According to Coulombs Law, two like electrical charges repel each other with a force that is inversely proportional to the square of the distance between them. If the force of repulsion is 10 dynes (1 dyne = 10E-5 newton) when they are 2 cm apart, find the work done in bringing the charges from 5 cm apart to 1 cm apart.
