Question

Given the surface charge density,ρs =2μ c/m2 , exsisting in region ρ=0.2m, z=0, find E at (a) PA(ρ=0, z=0.5); (b) PB(ρ=0, z=-0.5).

Answer 1

Answer:

Step 1 of 4

(a)

Note that there will be a single -component of will be present. Calculate the electric field at point using the following method.

Assume that a general point z on the -axis have the following distance vector,

Similarly, calculate the value of as,

Hence, calculate the distance between the two points as,
