Question

Coulomb's law of electrostatic force between two point charges and Newton's law for gravitational force between two stationary point masses both have in Inverse Square dependenceon the distance between the charges and masses respectively
(a) compare the strength of these forces by determining the ratio of their magnitudes (i) for an electron and a Proton and (ii) for two protons (b) estimate the acceleration of electron and proton due to the electrical force on their mutual attraction when they are 1 A° apart .​

Answer 1

Answer:

like charge repel each other

unlike charge attached each other.

f=1/4π€°×q1q2/r2

f = 1/r3
