In a regular polygon of n sides, each corner is at a distance r from the centre. Identical charges are placed at (n - 1) corners. At the centre, the intensity is E and the potential is V. The ratio V/E has magnitude (a) rn (b) r(n - 1) (c) (n - 1)/r (d) r(n - 1)/n |

Answer» Correct Answer is: (b) r(n - 1) At the centre, the intensity is effectively due to one charge and the potential is due to (n - 1) charges. |
