Question

Graph shows the variation of potential (V), magnitude of electric field (E), charge enclosed ( q enclosed ​ ) within the concentric sphere and net flux ( ϕ ) through a concentric spherical Gaussian surface as a function of distance ( r ) from centre of a uniformly positive charged solid sphere of radius R . Choose the CORRECT option(s).

TestHub · Accepted Answer

For a uniformly charged solid sphere, V falls as 2 R 3 3 R 2 − r 2 ​ inside and as r 1 ​ outside - (A) correct. E rises linearly up to r = R and falls as r 2 1 ​ outside - (B) correct. q e n c l ose d ​ grows as r 3 up to R and stays constant beyond - (C) correct. Net flux equals q e n c l ose d ​ / ϵ 0 ​ , so it must saturate, not peak and decay - (D) wrong.
