Two charged bodies exert an electrostatic force of 144 n on, Ask an Expert

Academics

Q. Two charged bodies exert an electrostatic force of 144 N on each other. If the distance between them is quadrupled and the magnitude of one charge is cut in half, what is the new force between them?

Q. A positive charge of 8.33 x 10^-5 C experiences a force of .109 N when located at a certain point. What is the electric field intensity at that point?
