1. Two point charges are separated by 6 cm. The attractive force between them is 20 N. (a) Find the magnitude of the electric force between the two charges when they are 12 cm apart. (b) If the charges
attracting each other have equal magnitudes, what is the magnitude of each charge? (c) How many
electrons are contained in the charge you found in part (b)?
