Answer 1

Assume that it is zero at a distance X from m1 .. Then it will be r-x will be far from m2. . add them vectorially. And equate it to zero. U will get X and then u can find potential diff.. Cause the word potential has no meaning

Answer 2

Hey mate.....

here's ur answer.....

Let the distance from X to m1 be 0..

Then r-x will be far from m2

Finally taking them out add them and equate it to 0...
This will give us the value of X and hence potential difference can be found.

Hope it helps
