Question

A body has a charge of −2μC. If it has 2.5×10^12 protons, then how many electrons the body has?

​

Answer 1

Explanation:

may be it is hepful to u.........

Answer 2

Explanation:

Total charge on the body equals the difference of charge due to protons and charge due to electrons.

−2×10−⁶=(2.5×10¹³−n)×1.6×10−¹⁹

n=3.75×10¹³
