MCQ
The specific charge of an electron is
- A$1.6 \times {10^{ - 19}}coulomb$
- B$4.8 \times {10^{ - 10}}stat\;coulomb$
- ✓$1.76 \times {10^{11}}coulomb/kg$
- D$|8| \times {10^{ - 15}}Hz$
✓
Answer
Correct option: C.
$1.76 \times {10^{11}}coulomb/kg$
c
(c) $\frac{e}{m} = \frac{{1.6 \times {{10}^{ - 19}}}}{{9.1 \times {{10}^{ - 31}}}} = 1.76 \times {10^{11}}C/kg$
(c) $\frac{e}{m} = \frac{{1.6 \times {{10}^{ - 19}}}}{{9.1 \times {{10}^{ - 31}}}} = 1.76 \times {10^{11}}C/kg$
