Two charges, 3.0 C and 4.0 C are located at (-0.50 m, 0) and (0.50

Question:

Two charges, – 3.0 μC and – 4.0 μC are located at (-0.50 m, 0) and (0.50 m, 0), respectively. There is a point on the x-axis between the two charges where the electric field is zero.
(a) Is that point (1) left of the origin, (2) at the origin, or (3) right of the origin?
(b) Find the location of the point where the electric field is zero.
