Question

an 18.75x10^18 free electrons are transferred to a 3.5 Coulmb positively charged dielectric,wa is it net charge?

Answer 1

1 electron charge = 1.60217646 × 10^-19 coulomb

so total charge of electron =

18.75x10^18   *    1.60217646 × 10^-19  =30.04 x10^-1  C

=3.004C

Net charge = charge on dielectric + charge of electron

=3.004 C +  3 C

=6Coulomb

Answer 2

it should be  around  6 columb.

total charge of electrons = 18.75 x10^18 X 1.6x10 ^-19 ~ 3.0

to total charge on dielectric 3.5 + 3.0  ~ 6 coloumb
