## Homework Statement

Three charges, Q1, Q2, and Q3 are located in a straight line. The position of Q2 is 0.323 m to the right of Q1. Q3 is located 0.125 m to the right of Q2

In the above problem, Q1 = 1.37 μC, Q2 = -2.53 μC, and Q3 = 3.43 μC. Calculate the total force on Q2. Give with the plus sign for a force directed to the right.

## Homework Equations

F=kq1q2 / r^2

## The Attempt at a Solution

I used the above formula to find the force for charge 1-2, and charge 2-3, and then added them together. I got the wrong answer.

My answers were: 0.29867 N + 4.99 N = 5.29 N

What am i doing wrong !?
