A small charged sphere with mass m hangs on a long string of length L. Another small charged sphere is brought near to the sphere on the string so that it no longer hangs vertically. The deviation of the ball from the initial vertical position is x. a) other charge, in terms of L, m, x, and gravitational acceleration g. Express F, the force exerted on the hanging charge by the b) length of the string is much larger than the deviation of the ball, i.e. that L >> x. Simplify your expression for the force assuming that the
