SATHEE: Electrostatics Question 810

Electrostatics Question 810

Question: Capacitance (in F) of a spherical conductor with radius 1 m is

Options:

A) $1.1 \times 10^{- 10}$

B) $10^{6}$

C) $9 \times 10^{- 9}$

D) $10^{- 3}$

Show Answer

Answer:

Correct Answer: A

Solution:

[a] Capacitance of spherical conductor

$4 π ε_{0} a$ where a is radius of conductor.

Therefore, $C = \frac{1}{9 \times 10^{9}} \times 1 = \frac{1}{9} \times 10^{- 9}$

$= 0.11 \times 10^{- 9} F = 1.1 \times 10^{- 10} F$
