Question

A comb drawn through person hair on a dry day causes 10 to the power 22 electrons to leave the persons hair and stick to the comb. calculate the charge carried by the comb

Answer 1

hell friend...!!!

we should calculate the charge carried by the comb ,

⇒ charge on the comb = total charge present = 10²² x $q_{e}$

here ,$q_{e}$ denotes value of charge ,

therefore the charge carried by the comb is ,

⇒ 10²² x 1.6 x 10⁻¹⁹ c

⇒ 1.6 x 10 ³ C is the charge carried by the comb .

Answer 2

Answer:

q=-ne

=-10^22×1.6×10^-19

=-1.6×10^3c
