Question

A 14.0-cm-long uniformly charged plastic rod is sealed inside a plastic bag. The net electric flux through the bag is 7.50×10^5 Nm2/C. 1) What is the linear charge density (charge per unit length) on the rod? (Express your answer to three significant figures.)

Explanation / Answer

l = 0.14 m

flux = 7.5*10^5 Nm2/C

Flux = q/e0

q = 7.5*10^5*8.85*10^-12 = 66.375*10^-7 C

linear charge density = q/l = 4.74*10^-5 C/m
