Concept

Problem: The electric field 5.40 cm from a very long charged wire is (2100 N/C , toward the wire).What is the charge (in nC) on a 1.00-cm-long segment of the wire?

FREE Expert Solution

The electric field from a charged wire:

E=-2kλr

From the equation:

λ = - (Er/2k) = - (2100)(5.40 × 10-2)/(2)(9 × 109) = - 6.3 × 10-9 C/m
