## shefaa 2 years ago 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.)

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

d is from centre of body or...

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
