The ratio of charge [e] to mass [m] is defined as specific charge. ∴ Specific charge =(e/m) For electron e=1.6 × 10-19 C, m=9 × 10-31 kg ∴ Specific charge =(1.6 × 10-19/9 × 10-31) =1.76 × 1011 C / kg

Q. The specific charge of an electron is

$1.6 \times 1 0^{- 19} C$

$4.8 \times 1 0^{- 19}$ stat $- C$

$1.76 \times 1 0^{- 11} C / k g$

$1.76 \times 1 0^{11} C / k g$

The ratio of charge $[e]$ to mass $[m]$ is defined as specific charge.
$∴$ Specific charge $= \frac{e}{m}$
For electron $e = 1.6 \times 1 0^{- 19} C,$
$m = 9 \times 1 0^{- 31} k g$
$∴$ Specific charge $= \frac{1.6 \times 1 0 ^{- 19}}{9 \times 1 0 ^{- 31}}$
$= 1.76 \times 1 0^{11} C / k g$

Q. The specific charge of an electron is

1.6×10−19C

4.8×10−19 stat −C

1.76×10−11C/kg

1.76×1011C/kg

The ratio of charge [e] to mass [m] is defined as specific charge. ∴ Specific charge =me​ For electron e=1.6×10−19C, m=9×10−31kg ∴ Specific charge =9×10−311.6×10−19​ =1.76×1011C/kg

$1.6 \times 1 0^{- 19} C$

$4.8 \times 1 0^{- 19}$ stat $- C$

$1.76 \times 1 0^{- 11} C / k g$

$1.76 \times 1 0^{11} C / k g$
