Question

A body has a negative charge of I coulomb. It means that it has

• A. lost one electron
• B. acquired one additional electron
• C. lost $6.25\times {10}^{18}$ electrons
• D. acquired $6.25\times {10}^{18}$ additional electrons

Answer 1

Answer: (D)

acquired $6.25\times {10}^{18}$ additional electrons

When the charge of a body is negative, it acquires excess of electron.

If n be number of excess of electrons then charge $q=ne$.

So, $n=\frac{q}{e}=\frac{-1}{1.6\times {10}^{-19}}=6.25\times {10}^{18}$
