Question

UM CORPO POSSUI 6,0.10^ protons e 4.0.10^19 eletros a carga elementar 1,6.10^-19 qual a carga deste corpo

Answer 1

6,0 . 10^19  protons

4,0 .10^19  eletrons

(6 .10^-19) - (4 .10^19) =  2 .10^19 protons   (a mais)

e = 1,6 .10^-19

Q = n . e             Q = 2.10^19 . 1,6.10^-19           Q= 3,2 C
