(a) Given two point charges, Q and 2Q, a distance d apart, is there a point along the straight line that passes through them where E = 0 when their signs are opposite? If yes, state roughly where this point will be.(b) Given two point charges, Q and 2Q, a distance d apart, is there a point along the straight line that passes through them where E = 0 when their signs are the same?
