Question

The electric field intensity due to an infinite cylinder of radius R and having charge q per unit length at a distance rir r(r > R) from its axis is
(a) directly proportional to r².
(b) directly proportional to r3.
(c) inversely proportional to r.
(d) inversely proportional to r².

Answer 1

crt ans is c opt

E = lamda/ 2Πr Eo

so its is inversely proportional to r

thank u❤
