Question

(B) Coulomb's law states that the electrostatic force between two point charges $q_1$ and $q_2$ separated by a distance $r$ is given by $F = k \frac{q

Vedclass · Accepted Answer

Because the electrostatic force between two charges is equal in magnitude and opposite in direction.

Vedclass · Answer

(B) Coulomb's law states that the electrostatic force between two point charges $q_1$ and $q_2$ separated by a distance $r$ is given by $F = k \frac{q_1 q_2}{r^2}$.According to Newton's $3^{rd}$ law,for every action,there is an equal and opposite reaction.When charge $q_1$ exerts a force $F_{12}$ on charge $q_2$,charge $q_2$ exerts an equal force $F_{21}$ on charge $q_1$ in the opposite direction.Mathematically,this is expressed as $\vec{F}_{12} = -\vec{F}_{21}$.Since the electrostatic forces between two charges are always equal in magnitude and opposite in direction,Coulomb's law is consistent with Newton's $3^{rd}$ law of motion.
