Question

Electric field and potential inside hollow charged conducting sphere are respectively
where $q$ and $r$ are the charge and radius of given sphere

• A. $0,0$
• B. $0, \frac{1}{4\pi\varepsilon_{0}} \frac{q}{r}$
• C. $ \frac{1}{4\pi\varepsilon_{0}} \frac{q}{r^{2}}, 0$
• D. $ \frac{1}{4\pi\varepsilon_{0}} \frac{q}{r^{2}}, \frac{1}{4\pi\varepsilon_{0}} \frac{q}{r}$

Answer 1

Answer: (B)

$E=0$, inside a hollow conducting sphere
$V$= potential at any point inside = potential at the surface $ =\frac{q}{4\pi\varepsilon_{0} r}$.
