Homework Help: Physics - Charges at an angle (check + help)

Posted by Anonymous on Wednesday, October 27, 2010 at 4:03am.

Three charged objects are located t the vertices of a right triangle. Charge A (5*10^-6) has Cartesian coordinates (0,4; Charge B (-5.0*10^-6) is at the origin; charge c (+4.0*10^-6) has coordinates (5,0), where the coordinates are in meters. What is the net force on each charge.

Ans: I found the charge on B by finding the force F(a to b) and similarly the hypotenuse force and using the cosine rule and sine rule i found the direction and the net charge but when i try the same on point charges A and C i do not get the answer. Where am i going wrong?
