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 charge Q uniformly distributed on the surface is given by $\frac{Q}{4\pi {ϵ}_{0}R}$.

• 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

Answer 1

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

Earthing system provides certain level of safety to humans and property in case of equipment damages. Earth is the reference point in an electrical circuit from which voltages are measured, a common return path for electrical circuit.
