## Homework Statement

Hi, Im working on the following question.

A 64 µC charge is located 30cm to the left of a 16 µC charge. What is the resultant force on a -12 µC charge positioned exactly 50mm below the 16 µC charge?

## Homework Equations

Coulombs law

## The Attempt at a Solution

I see a right triangle So I tried to solve using the vector components as follows

Fac=9.0e9(65x10e-6 * 12x10e-6)/(.3^2+.05^2) = 74.72C

Fbc = 9.0e9(16x10e-6 * 12x10e-6)/(.05^2) = 691.2C

For the rest, I'm not sure if I'm attacking this thing properly to solve for the vectors? I've tried at least 6 times... but no luck.

I could use a little direction...I attached a picture of the problem. My be helpful if it show's up.
