1. Responda as questões sobre quantização de carga a) Um corpo possui carga elétrica de \( 1,2 \times 10^{-6} \mathrm{C} \). Sabendo-se que a carga elétrica fundamental é \( 1,6 \times 10^{-19} \mathrm{C} \), encontre quantos elétrons estão em falta nesse corpo. b) A carga elétrica de um corpo é sempre múltipla da carga fundamental, de um único elétron, cujo módulo é igual a \( 1,6 \cdot 10^{-19} \mathrm{C} \). Se um corpo perder \( 2,0.10^{11} \) elétrons, então, qual sua carga elétrica total?
