3. When 10^14 electrons are removed from a neutral metal sphere, the charge on the sphere becomes
Α. 32 με
Β. 16 με
C. -16 με
D. -32 με

Β. 16 με

Explanation:

Data provided in the question

Number of electrons removed = 10^14

And, the charge on one electron =

Based on the above information, the charged on the sphere is

Therefore when we remove the electrons

So, the equation would be

=

Therefore the same amount of the positive charged would be developed

Hence, the correct option is B.
