SATHEE: Electrostatics Question 99

Electrostatics Question 99

Question: A $700 p F$ capacitor is charged by a $50 V$ battery. The electrostatic energy stored by it is [MH CET 2000]

Options:

A) $17.0 \times 10^{- 8} J$

B) $13.6 \times 10^{- 9} J$

C) $9.5 \times 10^{- 9} J$

D) $8.7 \times 10^{- 7} J$

Show Answer

Answer:

Correct Answer: D

Solution:

$U = \frac{1}{2} C V^{2} = \frac{1}{2} \times 700 \times 10^{- 12} {(50)}^{2}$

$= 8.7 \times 10^{- 7} J$
