Question

In one experiment the electric field is measured for points at distances r from a uniform line of charge that has charge per unit length λ and length l, where l≫r. In a second experiment the electric field is:

Answer 1

Answer:

(a) A. Uniform line of charge and B. Uniformly charged sphere

(b) To three digits of precision:

λ = 1.50 * 10^-10 C/m

p = 2.81 * 10^-4 C/m^3
