Current due to a Moving Line of Charge

EANDM-XB97IK

A long line of uniform charge density $\lambda = 3 \mu \frac { \text {C}}{m}$ is moving along the $+\widehat x$ direction with a constant speed of $v = 15 \: \frac{\text m}{\text s}$.

What is the value of the current created by this moving line of charge density?

A

$45 \: \mu \text A$

B

$5.0 \: \mu \text A$

C

$20 \:\text{mA}$

D

$1.25 \: \text A$

E

$67 \: \mu \text A$
