ANSWER

Three particles each of mass 1 g and carrying a charge q are suspended from a common point by insulated massless strings, each 100 cm long. If the particles are in equilibrium and are located at the corners of an equilateral triangle of sides of length 3 cm, calculate the charge q on each particle. Take g = 10 m s². 9
