When Q3 is placed between Q1 and Q2, it will cause the charge to move like this: <--Q1 (+), Q3 (+)-->, Q2 (-) So overall, the charge does cancels out.

Would you set up Q3 to be between Q1 and Q2?

I thought that "charge Q3 is located 0.169 m to the right of Q2" means that the point charges are at this order Q1---------Q2----.169-------Q3 Are the point charges supposed to be at this order: Q1------Q3-----Q2?

Homework Statement Three charges, Q1, Q2 and Q3 are located on a straight line. The charge Q3 is located 0.169 m to the right of Q2. The charges Q1 = 1.56 μC and Q2 = -3.03 μC are fixed at their positions, distance 0.268 m apart, and the charge Q3 = 3.18 μC could be moved along the line. For...
