Use Coulomb's law, F = kq1 Q2 /d^2, to calculate the electric force on an electron (Q = - 1.6 \times 10^- 19C exerted by a single proton if the particles are 0.53 \times 10^ - 10m apart. The constant k in Coulomb's law is 9.0 times 10^N* m^2/ C^2. The unit abbreviated N is the Newton, the SI unit of force.
