An infinitely long cylindrical shell of radius 6.0 cm carries a uniform surface charge density $\sigma$ = 12 nC/m².The electric field at r = 5.9 cm is approximately A)0.81 kN/C B)zero C)1.3 kN/C D)12 kN/C E)0.56 kN/C

Question

Quizplus · Accepted Answer

Since the electric field inside a uniformly charged cylindrical shell is zero, the electric field at r = 5.9 cm, which is inside the cylinder, is also zero. Hence, the correct answer is option B) zero.

An Infinitely Long Cylindrical Shell of Radius 6 σ\sigmaσ = 12 NC/m2

An Infinitely Long Cylindrical Shell of Radius 6 $\sigma$ = 12 NC/m²
