2. Electric Potential and Capacitance
easy

$R$ ત્રિજયાના ગોળીય કવચમાં કેન્દ્રથી અંતર $r$ નો વિદ્યુતસ્થિતિમાન $V$ વિરુધ્ધનો આલેખ કેવો થાય?

A
B
C
D

Solution

(b) ${V_{inside}} = \frac{Q}{{4\pi {\varepsilon _0}R}}$ for $r \le R$ ….$(i)$
and ${V_{out}} = \frac{Q}{{4\pi {\varepsilon _0}r}}$ for $r \ge R$ ….$(ii)$
i.e. potential inside the hollow spherical shell is constant and outside varies according to $V \propto \frac{1}{r}$.
