Question

the charge of an object is given by q=ne where n is number of electrons and e is electronic charge .if an object has charde -5x10power 18 what is thenumber of excess electron​

Answer 1

Explanation:

charge of an object is -5×10^18

so we know q = ne

charge of electron is 1.60217662 × 10^-19

• -5×10^18=n1.60217662 × 10^-19
• n=(-5×10^18)/(1.60217662 × 10^-19)
• n=-3.1210^37
