Question

Ratio of electrostatic and gravitational force between an electron and a proton

Answer 1

Explanation:

q is the charge of a proton, a 1.60*10^-19 C. Assuming their distance is constant, the ratio of gravitational to electrostatic force is basically G(m1)(m2) : (q1)(q2)/(4πεο). Plugging in the numbers, you'll find that the electrostatic force is 1.236*10^36 times stronger than the gravitational force.
