Question

What do you mean by coulomb's force is analogous to gravitational force

Answer 1

Dear student,

The coulombs Force and gravitational Force are comparable.They have similar form.

$$\begin{gathered} CoulombsforceF=k\frac{q_a{q}_b}{r^2} \\ GravitationalGorceF=G\frac{M_a{M}_b}{d^2} \end{gathered}$$

The difference is that gravitational force are always attractive and are weaker but coulombs force is either attractive or repulsive and much stronger.

Regards.
