Question
TWO EQ. +VE CHARGES R KEPT AT PT A & B D ELECTRIC POTENTIAL AT D PT B/W A & B (EXCLUDING THESE POINTS ) IS STUDIED WHILE ,MOVING FROM A TO B D POTENTIAL DECREASE THEN INCREASE WHY???
Joshi sir comment
at start when the point will be nearer to first charge, potential due to the nearer charge will be very high, at the middle point of the two charges it will be minimum and after that it will increase again due to its approach towards another charge.
