A charge q is placed at origin. Claculate the potential diffrence b/w the points ( a/ root 2, a/ root 2) and ( 3a/5, 4a/5)....

Dear Princes Cutie,

First of all understand that the origin here is reference u would use to find pd between any two points placed any where.. First calculate the pd between origin and the two points seperartely...and then get the difference between two and that gives the answer.. The only advantage of providing origin the reference is that it would have no effect on pd of any two points..
