Two metal balls are dropped from the top of a two-story building at the same time. One ball is twice as heavy as the other ball. Which statements about their motion are true? Assume that air resistance isn’t a factor.

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
