1) how far apart must two protons be if the magnitude of the electrostatic force on either one due to the other is equal to the magnitude of the gravitational force on a proton at Earth's surface?

2) An electron on the axis of an electric dipole is 2.5nm from the center of the dipole. What is the magnitude of the electrostatic force on the electron if the dipole moment is 3.6 x 10^-29 C.m? assume that 25nm is much larger than the dipole charge separation.
