Question

Find the ratio of the electric charge to gravitational forces between two protons

Answer 1

Gravitational force between two objects is given by F=G(m1)(m2)/(r^2).

G is the universal gravitational constant with the value of 6.67*10^-11.

m is the rest mass of a proton, at 1.67*10^-27 kg.

Electrostatic force between two charges is given by F=(q1)(q2)/(4πεο r^2).
