## Homework Statement

three point charges are placed at the following points on the x-axis +2 uC at x=0, -3uC at x=40 cm, -5 uC at x=120 cm. find the force (a) on the -3 uC charge, (b) on the -5 uC charge

ans. (a) -0.55N ; (b) 0.15 N

uC=nano coulomb

## Homework Equations

Fm=qvB ?

Fe=|E|(q)?

Fe=kq1q2/r^2

## The Attempt at a Solution

I cannot seem to solve such a simple problem, i need sufficient help. I have the idea that it has something to do with minusing each Fe charge by eachother but im uncertain please need help with a solution
