In a Classroom on the First Spaceship to an Extrasolar $\lambda$

Multiple Choice

In a classroom on the first spaceship to an extrasolar planet - there are children because the trip will take 200 years - a teacher is showing charge Q uniformly distributed along a conducting rod of length L0 to produce linear charge density $\lambda$ 0. As observed on Pluto when the spaceship passes it at 0.800 c, the linear charge density is:

A) 0.360 $\lambda$ 0.
B) 0.600 $\lambda$ 0.
C) 0.800 $\lambda$ 0.
D) 1.00 $\lambda$ 0.
E) 1.67 $\lambda$ 0.
