Question

2. Coulomb's law of electrostatic force between two
charges gives the value of force as F=k. 9192 Value
p2
of k, in C.G.S. system, is :​

Answer 1

Explanation:

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. (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 accelerations of electron and proton due to the electrical force of their mutual attraction when they are 1
