Question

The charges and coordinates of two charged particles held fixed
in an *xy* plane are *q*_{1} = 3.09 μC,
*x*_{1} = 3.70 cm, *y*_{1} = 0.604 cm
and *q*_{2} = -5.45 μC, *x*_{2} =
-2.27 cm, *y*_{2} = 1.52 cm.

Find the **(a)** magnitude and **(b)**
direction (with respect to +x-axis in the range (-180°;180°]) of
the electrostatic force on particle 2 due to particle 1. At what
**(c)** *x* and **(d)** *y*
coordinates should a third particle of charge
*q*_{3} = 4.50 μC be placed such that the net
electrostatic force on particle 2 due to particles 1 and 3 is
zero?
