A poythene piece rubbed with wool is found to have a negative charge of 3x10^(-7)C. (a) Estimate the no. of electrons transferred(from which to which)? (b) Is there a transfer of mass from wool to polythene?

No of electrons=3*10-7/1.6*10-19=2*1012
Yes if electrons will transfer the mass will also transfer.
