Question

two point charges +9e and +e are kept at a distance x from each other. where should we place a 3rd. charge q on the line joining the two charges so that it may be in equilibrium​

Answer 1

Answer:

Two point charges +9e and +e are kept at a distance 'a' from each other. A third charge is placed at a distance 'x' from +9e on the line joining the above two charges. For the third charge to be in equilibrium 'x' is. The net force acting on charge should be zero.
