Problem
Three charges each of value q, are placed at the corners of an equilateral triangle. A fourth charge Q is placed at the centre of the triangle. [1978]
(1) If Q=−q, will the charges at the corners move towards centre or fly away from it.
(2) For what value of Q will the charges remain stationary? In this situation how much work is done in removing the charges to infinity?
