Question

A spherical volume contains a uniformly distributed charge of density 2·0×10-4 C m-3. Find the electric field at a point inside the volume at a distance 4⋅0 cm from the centre.

Answer 1

Given: Volume charge density = 2.0 × 10–4c/m3 In order to find the electric field at a point 4cm = 4 × 10–2m from the centre let us assume a concentric spherical surface inside the sphere.
