A q1 20 nc point charge and a q2 -40 nc point charge are

Question

A Q₁ = +2.0 nC point charge and a Q₂ = -4.0 nC point charge are 5.0 cm apart on the x-axis. Find the point on the x-axis where the electric field is zero.

You are required to draw Electric vectors for both charges at a point between the two charges, and also at a point outside of the two charges on the right side and on the left side of Q₂ and on the left side of Q₁

Then decide at which of these points the net electric force is zero and show the complete solution.
