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

Explanation:

mass of the proton is given is

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

now we need to find the charge mass ration of proton

so here we have

So above is the charge mass ratio of proton

it becomes positively charged by charging it

answer(20) psi;
