(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Positive charges are situated at three corners of a rectangle, as shown in the attachment. Find the electric field at the fourth corner.

the numbers are: bottom left- 3.00 nC bottom right-5.00 nC top right- 6.00 nC

the length of the rectangle is .6 m and the width is .2 m

2. Relevant equations

F=K q1/r^2

3. The attempt at a solution

I found all of the forces

F1= 9*10^9 (3*10^-9/.2^2) =675 n/C

F2= 9*10^9(5*10^-9/.63^2) =113 n/C

F3= 9*10^9(6*10^-9/.6^2) =150 n/C

Then I know you have to combine vectors and get the answer, but that's what I'm having trouble doing.

Please help!!

Thanks in advance
