Question

A cylinder with radius r = 0.75m and length l = 0.6m that has an infinite line of positive charge running along its axis. The charge per unit length in the line is 7µc/m.

i. What is the electric flux through the cylinder due to this line of

charge? 

ii. What is the flux through the cylinder if its radius increased to r =

0.32m?

iii. What is the electric field intensity at radius r = 0.32m and l =

0.6m? 

iv. What is the flux through the cylinder if its length increased to     l=0.8m? 

v. What is the electric field intensity at radius r= 0.32 and l=0.8m?

vi. Briefly explain the effect of an increase or decrease of radius and length on the electric field intensity.
