Question

A polythene piece rubbed with wool is found
to have a negative charge of 3 x 10-7C. Estimate
the number of electrons transferred from
which to which?​

Answer 1

Answer:

The charge is on polythene is q=ne

but we have q=3 x 10-7c

so,q=ne

n=q/e

{e=1.6*10-19c}

n=3×10-7/1.6×10-19

n=1.875×10¹²
