Question

Mention the specific charge of proton.

Answer 1

Calculating the specific charge of proton:

• Specific charge is defined as the charge to mass ratio of proton.

As we know that,

${\mathrm{q}}_{\mathrm{p}}=1.602\times {10}^{-19}\mathrm{C}$

$m_{\mathit{p}}\mathit{=}\mathit{1}\mathit{.}\mathit{673}\mathit{\times }{\mathit{10}}^{\mathit{-}\mathit{31}}Kg$

Step 1: Calculating the charge to mass ratio of proton:

$\frac{{\mathrm{q}}_{\mathrm{p}}}{{\mathrm{m}}_{\mathrm{p}}}=\frac{1.602\times {10}^{-19}\mathrm{C}}{1.673\times {10}^{-27}\mathrm{Kg}}$

$\frac{{\mathrm{q}}_{\mathrm{p}}}{{\mathrm{m}}_{\mathrm{p}}}=0.957\times {10}^8\mathrm{C}/\mathrm{Kg}$

$\frac{{\mathrm{q}}_{\mathrm{p}}}{{\mathrm{m}}_{\mathrm{p}}}=9.57\times {10}^7\mathrm{C}/\mathrm{Kg}$

Final Answer:

Therefore, the charge to mass ratio of proton is $9.57\times {10}^7\mathrm{C}/\mathrm{Kg}$.
