Question

An insulating solid sphere of radius a has a uniform volume charge density $\rho$ and total positive charge q.The strength of the electric field inside the sphere at a distance r from the center (r < a)is proportional to

Quizplus · Accepted Answer

For a uniformly charged solid sphere, the electric field inside the sphere is given by:
E = (1/3ε₀) * (q/a³) * r
Since the electric field is directly proportional to r, the correct choice is B.
