Electrostatics Question 77
Question: Two spherical conductors each of capacity $ C $ are charged to potentials $ V $ and $ -V $ . These are then connected by means of a fine wire. The loss of energy will be [MP PMT 1997]
Options:
A) Zero
B) $ \frac{1}{2}CV^{2} $
C) $ CV^{2} $
D) $ 2CV^{2} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ \Delta V=\frac{1}{2}\frac{C\times C}{(C+C)}|V-(-V){{|}^{2}}=CV^{2} $
