Question

Two very long parallel lines of charge are shown in figure, fixed in place, separated by d=12 cm. The uniform linear charge densities are ! = 0.004 C/m for line 1 and ! = 0.008 C/m for line 2.

Answer 1

Answer:

In the figure short sections of two very long parallel lines of charge are shown, fixed in place, separated by L = 8.0 cm. The uniform linear charge densities are +9.0

μ

C/m for line 1 and -2.6

μ

C/m for line 2. Where along the x axis shown is the net electric field from the two lines zero?

Electric Field due to Infinitely Long Line of Charge.

The electric field due to infinitely long line of charge is radially away from the line of charge if it contains the positive charge but it is radially inward if the line of charge contains the negative charge.
