1)A plastic rod is rubbed against a wool shirt, thereby acquiring a charge of -0.7 µC. How many electrons are transferred from the wool shirt to the plastic rod?

Respuesta :

Answer:

electrons are transferred from the wool shirt to the plastic rod is  4.375 × [tex]10^{12}[/tex] electrons

Explanation:

given data

Amount of charge transferred Q = -0.7 μC  = -0.7 × [tex]10^{-6}[/tex] C

electrons of charge e = -1.6 × [tex]10^{-19}[/tex] C

solution

we apply formula here for  total charge of electrons that is

Q = n × e   ...................2

here n is no of electron that is

n = [tex]\frac{Q}{e}[/tex]    

put here value

n = [tex]\frac{-0.7*10^{-6}}{-1.6*10^{-19}}[/tex]  

n = 4.375 × [tex]10^{12}[/tex] electrons

so here electrons are transferred from the wool shirt to the plastic rod is  4.375 × [tex]10^{12}[/tex] electrons
