Q 1.11(a): A polythene piece rubbed with wool is found to have a negative charge of . (a) Estimate the number of electrons transferred (from which to which?)
Clearly, polyethene being negatively charged implies that it has an excess of electrons(which are negatively charged!). Therefore, electrons were transferred from wool to polyethene.
Given, Charge attained by polyethene = C
We know, Charge on 1 electron =
Therefore, the number of electrons transferred to attain a charge of =
