MCQ
In a hollow spherical shell potential $(V)$ changes with respect to distance $(r)$ from centre
  • A


  • C

  • D

Answer

Correct option: B.

b
(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 $V \propto \frac{1}{r}$.

Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason $R$.

Assertion $A$ : If $dQ$ and $dW$ represent the heat supplied to the system and the work done on the system respectively. Then according to the first law of thermodynamics $d Q=d U-d W$.

Reason $R :$ First law of thermodynamics is based on law of conservation of energy.

In the light of the above statements, choose the correct answer from the option given below :
