Homework Statement
Four charged particles are placed so that each particle is at the corner of a square. The sides of the square are 17 cm. The charge at the upper left corner is +4.0 µC, the charge at which the upper right corner is -5.0 µC, the charge at the lower left corner is -2.9 µC, and the charge at the lower right corner is -9.1 µC.
a) What is the magnitude of the net electric force on the +4.0 µC charge? (In Newtons).
b) What is the direction of this force (measured from the positive x-axis as an angle between -180 and 180, with counterclockwise positive? Answer in units of degrees.
c) What is the magnitude of the net electric force on the -5.0µC charge? (Answer in units of Newtons.)
Homework Equations
The Coulomb constant is 8.98755 x 10^9 N.
The Attempt at a Solution
I hope I posted this correctly, if not, I'm sorry for the trouble!
Thanks so much for the help, I've been trying to figure this out for days and just don't get it...There's another part to the problem that I might need help with, but I have to figure this part out first.
