Question

Why Coulomb force is called "Mutual Force"???????????????????????????????????????

Answer 1

Answer

The Columb's law is the same as Gravitational law

Explanation

As we see the formula of both Coulomb and Gravitational Law,

$F_g = GM_1M_2/R_2$     (1)

$F_c = kq_1q_2/r_2$         (2)

The masses (M) in formula (1) experiencing the force of gravitational pull with each other which varies with changing the distance. In the formula (2), the charges also are felling the forces on each other which varies with distance. The charges and masses are just like the objects which are experiencing the forces which have a common factor as distance. The gravitational force is also called the mutual forces.
