Question

56. A surface completely surrounds a +2.0 x 10-6 C charge. Find the electric flux through this surface when the surface is (a) a sphere with a radius of 0.50 m, (b) a sphere with a radius of 0.25 m, and (c) a cube with edges that are 0.25 m long.

Answer 1

Approach used:- here we use the Gauss's law for flux through a closed surface when the surface encloses a charge,
