Net charge on object having `9 xx 10^13` protons and `6 xx 10^13` electrons is ......

A

`-4.8 muC`

B

`4.8 muC`

C

`4.8C`

D

`3 xx 1.6 xx 10^(-19)` C

Text Solution

Verified by Experts

The correct Answer is:
B
Net charge `=9 xx 10^(13) xx 1.6 xx 10^(-19) - 6 xx 10^(13) xx 1.6 xx 10^(-19)`
`=4.8 xx 10^(-6) muC`
