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

question 12

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.
