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}} $
