Practicing Success
A given charge situated at a certain distance from an electric dipole in the end on position experiences a force F. If the distance of the charge is doubled, the force acting on the charge will be |
2 F F/2 F/4 F/8 |
F/8 |
$ F \propto \frac{1}{r^3}$ If r is doubled then F becomes one eigth of original value |
