Charges and Forces

Please show all work and diagrams plus equations used to solve problem. Thanks!

1) A small object has charge Q. Charge q is removed from it and placed on a second small object. The two objects are placed 1 meter apart. For the force that each object exerts on the other to be a maximum, q should be:

2) Two small charged objects repel each other with a force F when separated by a distance d. If the charge on each object is reduced to one-fourth of its original value and the distance between them is reduced to d/2 the force becomes?

Solution Summary

The solution provides explanations and step-by-step calculations for finding the force a charged objects exerts on another, as well as the change in force as two charged objected repel each other.
