## Homework Statement

A charge +2nC is located at (0, 2 m). Another +2 nC charge is

located at (0, -2 m). A third charge, +3 nC, is located at (2 m, 0).

Calculate the total force (in vector form) acting on charge +3nC

from both +2nC charges.

## Homework Equations

Coulomb's law in vector form

## The Attempt at a Solution

I worked out the force on q3 due to q1 to be:

9.54 nano Newton in the positive x direction and

-9.54 nano Newton in the negative y direction

Next, I worked out the force on q3 due to q2 and got:

9.54 nano Newton in the positive x direction and in the positive y direction.

Adding these together, the component would be zero and the total force would be 19.08 nano Newton in the x direction. This would be my answer. However, the answer given is 9.537 nano Newton in the x direction.

Any help is appreciated!

Thanks
