Question

The mass of a proton at rest is 1.67 10 2kg . Calculate the value of e/m for a proton.

Answer 1

Answer:

$\frac{e}{m} = 9.58 \times 10^7$

Explanation:

mass of the proton is given is

$m_P = 1.67 \times 10^{-27} kg$

also we know that charge of proton is same as charge of electron

$e = 1.6 \times 10^{-19} C$

now we need to find the charge mass ration of proton

so here we have

$\frac{q}{m} = \frac{1.6 \times 10^{-19}}{1.67 \times 10^{-27}}$

$\frac{e}{m} = 9.58 \times 10^7$

So above is the charge mass ratio of proton
