Question

The charges and coordinates of two charged particles held fixed inan xy plane are q1 = +2.0 µC, x1 = 3.0 cm, y1 = 0.50 cm, and q2 =-4.0 µC, x2 = -2.0 cm, y2 = 1.5 cm.

(a) Find the magnitude of the electrostatic force on q2.
____ N
(b) Find the direction of this force.
____° (counterclockwise from the +x axis)
(c) At what coordinates should a third charge q3 = +4.5 µC beplaced such that the net electrostatic force on particle 3 due toparticles 1 and 2 is zero?
x =_____cm
y =_____cm
