Question

A spherical shell of radius $10\, cm$ is carrying a charge $q$. If the electric potential at distances $5 \, cm, 10 \, cm$ and $15 \, cm$ from the centre of the spherical shell is $V_1, V_2$ and $V_3$ respectively, then respectively, then

• A. $V_1>V_2>V_3$
• B. $V_1 < V_2 < V_3$
• C. $V_1=V_2>V_3$
• D. $V_1 = V_2 < V_3$

Answer 1

Answer: (C)

$V_1=V_2>V_3$

Answer 2

Inside the spherical shell potential is same
$\Rightarrow V_{1}=V_{2}$
$V \propto \frac{1}{d}$
i.e. $V_{1}=V_{2} >\,V_{3}$
