JEE Advance 2008

Paper-2

Question

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

Select the correct option:

A

STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is a correct explanation for STATEMENT-1

B

STATEMENT-1 is True, STATEMENT-2 is True; STATEMENT-2 is NOT a correct explanation for STATEMENT-1

C

STATEMENT-1 is True, STATEMENT-2 is False

D

STATEMENT-1 is False, STATEMENT-2 is True

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

Both the statements are true,& statement (II) is not the correct explanation of statement (I). Because, whatever be the value of potential we can assign it zero as a reference.
