Take q1=23uC at (0,1), q2=16uC. at (2,0), and q3=? at (2,2). IF the force on q1 points in the -x direction, (a) what is q3 and (b) what is the magnitude of the force on q1?
I know a is 16uC
For part B I got .067 am I right
I am using Coloumbs law
What am I doing wrong??
You have to figure each force on q1 (from q3, q3) and add them as VECTORS.
How do you do that
Josh, if you don't know how to add two ninety degree vectors, and you are now in statics, something is greatly wrong.
