Vedclass · Answer

(B) $STATEMENT-1$ is True because the Earth is a vast conductor and its potential is taken as a reference point (zero potential) for all electrical measurements.$STATEMENT-2$ is True because the potential at the surface of a charged conducting sphere is $V = \frac{1}{4 \pi \varepsilon_0} \frac{Q}{R}$.However,$STATEMENT-2$ does not explain why the Earth is chosen as the reference point. The choice of Earth as a reference is a convention based on its size and conductivity,not because of the specific potential formula of a sphere. Therefore,$STATEMENT-2$ is not the correct explanation for $STATEMENT-1$.

$STATEMENT-1$: For practical purposes,the Earth is used as a reference at zero potential in electrical circuits.
$STATEMENT-2$: The electrical potential of a sphere of radius $R$ with charge $Q$ uniformly distributed on the surface is given by $\frac{Q}{4 \pi \varepsilon_0 R}$.
