Question

when a piece of polythene is rubbed with wool,a charge of -2×10 to the power minus coulomb is developed on polythene ? what mass is transferred to polythene? ​

Answer 1

transferred mass = n×me

where, me is mass of electron and

n is number of electrons transferred

n= (2×10^ -1)/(1.6 × 10^ -19)

me = 9.1 × 10^-31 kg
