When ` 10^(14) ` electrons are removed from a neutrol metal sphere, the charge on the sphere becomes

A

`16 muC `

B

` -16 mu C `

C

` 32 mu C`

D

` -32 muC `

Text Solution

Verified by Experts

The correct Answer is:
A
Charge of ` 10^(14) ` electron `q= n e =10^(14) xx1.6 xx 10^(-19) C = 1.6 xx 10^(-5) C = 16 mu C .` As electron have been removed from metal sphere, it will acquire a positive charge of ` +16 muC . `
