MCQ
The specific charge of an electron is
  • A
    $1.6 \times 10^{-19}$ coulomb
  • B
    $4.8 \times 10^{-10}$ statcoulomb
  • $1.76 \times 10^{11}$ coulomb $/ \mathrm{kg}$
  • D
    $1.76 \times 10^{-11}$ coulomb $/ \mathrm{kg}$

Answer

Correct option: C.
$1.76 \times 10^{11}$ coulomb $/ \mathrm{kg}$
$\frac{e}{m}=\frac{1.6 \times 10^{-19}}{9.1 \times 10^{-31}}=1.76 \times 10^{11} \mathrm{C} / \mathrm{kg}$
