Give Coulomb's law in vector form. What is the significance of expressing it in the vector form?

### Asked by Topperlearning User | 17th Apr, 2015, 09:34: AM

If two charges q_{1} and q_{2} are kept at r distance apart then, according to Coulomb's law

Force on charge q_{2 }due to q_{1, }

Force on charge q_{1 }due to q_{2, }

As the Coulomb force acts along _{} or _{} i.e the line joining the centers of two charges, so they are the central force.
