3. When 10^14 electrons are removed from a neutral metal sphere, the charge on the sphere
1 answer:
Answer:
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.

Answer:-q
Explanation:
Given
Capacitor is charged to a battery and capacitor acquired a charge of q i.e.
+q on Positive Plate and -q on negative Plate.
If the plate area is doubled and the plate separation is reduced to half its initial separation then capacitor becomes four times of initial value because capacitor is given by
where A=area of capacitor plate
d=Separation between plates
This change in capacitance changes the Potential such that new charge on the negative plate will remain same -q
