Electrostatics Question 182
Question: When $ 10^{14} $ electrons are removed from a neutral metal sphere, the charge on the sphere becomes [Manipal JEE 1995]
Options:
A) $ 16\mu C $
B) $ -16\mu C $
C) $ 32\mu C $
D) $ -32\mu C $
Show Answer
Answer:
Correct Answer: A
Solution:
$ Q=ne=10^{14}\times 1.6\times {{10}^{-19}} $
therefore $ Q=1.6\times {{10}^{-5}}C=16\mu C $ Electrons are removed, so chare will be positive.
