What is meant by equipotential surface? Show that the amount of work done in moving a test positive charge along the equipotential surface is zero. |

Answer» SOLUTION :An EQUIPOTENTIAL surface is that at every point of which the electric POTENTIAL is same i.e., there is no difference of potential between any two points on it. Since potential difference `dV=(dW)/(q)` In an equipotential surface, `dV=0` `THEREFORE (dW)/(q)=0` or `dW=0` i.e. no work is done in moving a test charge ALONG the equipotential surface. |
