Two point charges are separated by a distance r and repel each other with a force F. If their separation is reduced to 0.280 times the original value, what is the magnitude of the force of repulsion between them?
I don't really understand this question and don't know where to start.
Would I start with the equation
E = ((k)(Q)/r^2
what follows next?
