You are given two unknown point charges, Q1 and Q2. At a point on the line joining them, one-third of the way from Q 1 to Q2, the electric field is zero. Are Q1 and Q2 like or unlike charges? How many times greater is Q2 than on Q1?

I am really confused on this problem. Please help me set it up. Thanks.
