Answer :
Answer:
1.92×10^-9 microCoulomb
Explanation:
Elemental charge = 1.6×10^-19 Coulomb
Charge of balloon after 12,000 electrons have been removed from it = 12,000 × 1.6×10^-19 Coulomb = 1.92×10^-15 Coulomb = 1.92×10^-15/10^-6 = 1.92×10^-9 microCoulomb
The charge of the balloon after 12000 electrons have been removed from it is [tex]1.92\times 10^{-9}\,\mu C[/tex]
Electric Charges
Electric charges are defined as the charge that is contained or carried by a body that can either be positive or negative.
The charge of a neutral balloon is zero. If electrons are removed from a neutrally charged balloon it will be positively charged.
[tex]1\,e = 1.6\times 10^{-19}\,C12000\,[/tex]
[tex]e =12000\times 1.6\times 10^{-19}=1.92\times10^{-9}\times[/tex][tex]10^{-6}\,[/tex]
[tex]10^{-9}\times C=1.92\times 10^{-9}\,\mu C[/tex]
So,
The net charge on the balloon is [tex]1.92\times 10^{-9}\,\mu C.[/tex]
