Question

Two electrons are at distance apart from one another.What is the order of magnitude of ratio of the electric force between them to the gravitational force between them

Answer 1

Answer:

Fe = K q^2 / R^2     electrical force

Fg = G m^2 / R^2     gravitational force

Fe / Fg = 9 * 10E9 * (1.6 * 10E-19)^2 / (6.67 * 10E-11 * (9.11 * 10E-31))^2

Fe / Fg = 4.16 * 10E42
