Question

17. Coulomb's law for electrostatic force between two point charges and Newton's law to
gravitational force between two stationary point masses, both have inverse-square dependene
on the distance between the charges/masses.
(a) Compare the strength of these forces by determining the ratio of their magnitudes
(1) For an electron and a proton
(ii) for two protons
(b) Estimate the accelerations of electron and proton due to the electrical force of their mutual
attraction when they are 1A(10-1°m) apart? (m. = 1.67 * 10-27 kg; m. = 9.11 10-9 kg​

Answer 1

Answer:

Coulomb's law for electrostatic force between two point charges and Newton's law for gravitational force between two stationary point masses, both have inverse-square dependence on the distance between the charges/masses. ... It acts along the line joining the two charges considered to be point charges.
