Question

If 10^12 electrons are removed from a neutral metal sphere find the charge

Answer 1

Answer:

charge of an electron=-1.6*10^-19 c

no of electrons removed 10^12

net charge =+1.6*10^-19*10^12=1.6*10^-7c

Answer 2

The electron is a subatomic particle whose electric charge is negative one elementary charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure

$10^{12}, q=ne=10^{12}\times 1.6 \times 10^{-19}=16 \times 10^{-17}C$

$q=0.16\mu C$ Electrons are removed so metal sphere becomes positive.
