A metal sphere has a charge of `-6 muC`. When `5xx10^(12)` electrons are removed from the sphere. What would be net charge on it ?

Text Solution

Verified by Experts

`q_(1)=6 muC`
`q_(2) ="ne" =5xx10^(12)xx(1.6xx10^(-19))`
`q_(2)=8.0xx10^(-7)C`
`=0.80xx10^(-6)C=0.8 mu C`
Since electrons are removed from the sphere, `q_(2)` is positive.
`:.` Net charge on the sphere,
`q=q_(1)+q_(2)`
`q=(-6.0+0.8)xx10^(-6)C`
`q=-5.2xx10^(-6)C`
