Two point charges q1= +5.5 µC and q2= −3.5 µC are 14 cm apart along x-axis (charge q1 is at the origin and charge q2 is at x=14 cm).

1) Discuss at what point (or points) on x-axis net electric field due to these two charges can be zero? Right side of them, left side of them, or between them? Discuss/justify your answer.

2) Find the point where the net electric field is zero. Let's call distance of this point from charge q1, x (x is unknown). Find x?
