Apolythene piece rubbled with wool is found to have a negative charge `3xx10^(-7)C`.
Is there a transfer of mass from wool to polythene?

Text Solution

Verified by Experts

The number of electrons transferred `=1.875xx10^(12)`
The mass of one electron, `m_(e)=9.1xx10^(-3)` kg
Mass transferred from wool to polythene `M=nxxm_(e)`
`M=1.875xx10^(12)xx9.1xx10^(-31)=1.8xx10^(-18) kg`
