Correct answer: C. a=R

In case of solid sphere of charge of uniform volume density. E=

\frac{1}{4 \pi \varepsilon_0} \cdot \frac{q}{R^3} \cdot

r

\text{ or }

E \propto r Thus, for

E

to be linearly dependent on

r

, volume charge density should be constant. or

\quad a=R\therefore

correct option is (c). Paragraph: The nuclear charge (Ze) is non-uniformly distributed within a nucleus of radius R . The charge density (r)
