Question

A cylinder of large length carries a charge of 2?10^-8Cperm find
the electric field at a distance of 2 0m from it

Sujatro Baral · Answer

Formula of the electric field (E) = kQ/r2 where k is a constant
with a value of 8 99 x 10^9 N m2/C2 Data: Charge (Q) = 2×10^8
C/m Distance (r)= 0 2m Solution: E = kQ/r2 = 8 99 x 10^9 N m2/C2 x
2×10^8 C/m / (0 2m) = 17 98 x10^17/0 04 = 4 495 x 10^19
