SATHEE: Electrostatics Question 83

Electrostatics Question 83

Question: What is the area of the plates of a $3 F$ parallel plate capacitor, if the separation between the plates is $5 m m$ [AIIMS 1998; Pb. PET 2000; BHU 2002]

Options:

A) $1.694 \times 10^{9} m^{2}$

B) $4.529 \times 10^{9} m^{2}$

C) $9.281 \times 10^{9} m^{2}$

D) $12.981 \times 10^{9} m^{2}$

Show Answer

Answer:

Correct Answer: A

Solution:

We have $C = \frac{ε_{0} A}{d}$

therefore $A = \frac{C d}{ε_{0}} = \frac{3 \times 5 \times 10^{- 3}}{8.85 \times 10^{- 12}}$

$= 1.7 \times 10^{9} m^{2}$
