If a charge on the body is 1 nC, then how many electrons are present on the body ?

Options

A. `6.25xx10^(27)`
B. `1.6xx10^(19)`
C. `6.25xx10^(28)`
D. `6.25xx10^(9)`

Answer

D

Explanation

Charge on the body is
`q= n e `
`:.` No. of the electrons present on the body is
`n=q/e= (1xx10^(-9)C)/(1.6xx10^(-19)C)=6.25xx10^(9)`
