Two negative point charges each of magnitude 2 esu and another point charge q are lying on a straight line. Each of the charges are in equilibrium. Determine the position, value and the nature of the charge q.

Two positive point charges Q and one negative point charge q are arranged in a straight line in such a manner that the complete system remains in equilibrium. What can be the magnituude of Q/q ?

Consider a point charge +q placed at the origin and another point charge -2p placed at a distance of 9 m from the charge +q . Determine the point between the two charges at which electric potential is zero.
