harge of uniform density (100 nC/m3) is distributed throughout a hollow cylindrical region formed by two coaxial cylindrical surfaces of radii 1.0 mm and 3.0 mm. Determine the magnitude of the electric field at a point which is 2.0 mm from the symmetry axis. Group of answer choices

The magnitude of the electric field is 8.47 N/C

Explanation:

Given;

uniform charge density, λ = 100 nC/m³

inner radii of the cylinder, r =  1.0 mm and 3.0 mm

distance from the symmetry axis, R = 2.0 mm

Area = 2πrl

Area =2π(2 x 10⁻)l

Volume = A x d

d = Volume / Area

the magnitude of the electric field

Therefore, the magnitude of the electric field is 8.47 N/C
