Question

An infinitely long line charge having a uniform charge per unit length λ lies a distance d from point O as shown in the figure below. Determine the total electric flux through the surface of a sphere of radius R centered at O resulting from this line charge. Consider both cases, where R < d and R > d. (Use any variable or symbol stated above along with the following as necessary: ε0.)

Answer 1

i don't understand why every one forgeting post image!!!!!!!!!!!!!!

Answer 2

d is from centre of body or...

Answer 3

heres the image

Answer 4

thnx friend for posting image:
for R<d
from gauss' law \[E=(\lambda/2\pi d \epsilon _{0})\]
so electric flux is:\[\phi=E.A \rightarrow \phi=(\lambda/2\pi d \epsilon _{0})*\pi R^2\]
i'm not sure about R>d.
i think are the same
