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 = 2.0 cm is approximately A)12 kN/C B)0.56 kN/C C)1.3 kN/C D)0.81 kN/C E)zero

Question

Quizplus · Accepted Answer

The electric field inside a uniformly charged infinite cylindrical shell is zero due to the symmetry of the problem. Gauss's law in electrostatics implies that the electric field inside the shell (r < radius of the shell) is zero because the enclosed charge is zero.
