Two point charges are located at the following locations:

q1= 2.5 × 10−5 C located at ~r1= <−4,3,0> m

q2= −5×10−5C located at ~r2= < 4,−3,0> m.

a) Calculate the net electric force on an electron located at the origin. Answer must be a vector.

b) Determine where to place a positive charge q3= 1.2×10−5C so that the net force on the electron located at the origin is zero.
