MCQ
100 C charge means a deficit of _________ electrons.
- A$6.25 \times 10^{18}$
- B$6.25 \times 10^{16}$
- ✓$6.25 \times 10^{20}$
- D$6.023 \times 10^{23}$
✓
Answer
Correct option: C.
$6.25 \times 10^{20}$
(c)
$6.25 \times 10^{20}$
Explanation:
We know that, charge on a body, $q= \pm n e$, charge of an electron is $-1.6 \times 10^{-19}$. Hence, 100 C charge is a deficit of, $100 /\left(1.6 \times 10^{-19}\right)=6.25 \times 10^{20}$ electrons.
$6.25 \times 10^{20}$
Explanation:
We know that, charge on a body, $q= \pm n e$, charge of an electron is $-1.6 \times 10^{-19}$. Hence, 100 C charge is a deficit of, $100 /\left(1.6 \times 10^{-19}\right)=6.25 \times 10^{20}$ electrons.
