Question

if 10^14 electrons are removed from a neutral metal sphere,then what is the charge on the sphere

Answer 1

no. of e- removed = 10^14
charge on one electron=1.6*10^-19C
so when we remove electrons..... -10^14*1.6*10^-19 C is removed.....so,
same amount of positive charge will be developed on that body but it will be positive as negative is removed

Answer 2

Answer:

The loss of electron will make the body positively charged.

On removing electrons, the body acquires positive charge and its value can be found by using quantization of charge.

According to this rule of quantization the charge remains conserved if any amount of electrons is removed from a particular body and the amount of new charge acquired by the body can be found with the help of the relationship.

$q=n e=10^{14} \times 1.6 \times 10^{-19} C=1.6 \times 10^{-5} \mathrm{C}$

Where n is the number of electrons removed and e is the charge on one electron.
