Question

In figure, short sections of two very long parallel lines of charge are shown, fixed in place, and separated by L = 8.0 cm. The uniform linear charge densities are + 6.0 μC/m for line 1 and – 2.0 μC/m for line 2. Where along the x-axis (from the origin) is the net electric field due the two lines zero?

A) 6.0 cm 

B) 4.0 cm 

C) 2.0 cm 

D) 8.0 cm 

E) 0.0 cm

Answer 1

Correct option is D) 8.0 cm

The point should be to the right of line z, at a distance (d) from it.
