Vedclass · Answer

(D) The charge on the plastic rod is $q = -8 	imes 10^{-7} \ C$. Since the rod becomes negatively charged,it has gained electrons.Using the quantization of charge formula,$q = ne$,where $e = 1.6 	imes 10^{-19} \ C$ is the magnitude of the charge of an electron.$n = \frac{|q|}{e} = \frac{8 	imes 10^{-7}}{1.6 	imes 10^{-19}}$$n = 5 	imes 10^{12}$Since the plastic rod gained a negative charge,electrons must have been transferred from the wool to the plastic rod.

Rubbing a plastic rod with wool gives the plastic rod a negative charge of $8 \times 10^{-7} \ C$. How many electrons have been transferred,and from where to whom?
