A body has a negative charge of 1 coulomb. It means that it has

A

lost one electron

B

acquired one additional electron

C

lost `6.25 xx 10^(18)` electrons

D

acquired `6.25 xx 10^(18)` additional electrons

Text Solution

Verified by Experts

The correct Answer is:
D

Numebr of electron acquired
`n=(q)/(e )`
`=( -1) /( - 1.6 xx 10^(-19))= 6.2 xx 10^(18)`
