A body has `-80 mu C` of charge. Number of additional electrons in it will be

A

`8 xx 10^(5)`

B

`80 xx 10^(15)`

C

`5 xx 10^(14)`

D

`1.28 xx 10^(-17)`

Verified by Experts

The correct Answer is:

C

Given, `q = - 80 muC = 0.80 xx 10^(-6) C`
Number of additional electrons,
`n = (q)/(e) = (-80 xx 10^(-6))/(-1.6 xx 10^(-19)) = 5 xx 10^(14)`
