There are 4 identical metal balls: J, K, L, M. Initially, J has charge Qui = 0e, L has charge QLi = -3e, and M has charge QMi = -35e. The ball J touches the ball K, and they separate. Then, the ball J touches the ball L, and they separate. Then, the ball J touches the ball M, and they separate. The final charge on the ball J is Qjf = -6e. What was the initial charge on ball K? Qki = ? (You must put a + or - sign on your answer, unless you get zero; for example +5e if positive, -10e if negative, Oe if zero.) There are 4 identical metal balls: J, K, L, M.
