The charge to mass ratio of an electron ...

The charge to mass ratio of an electron is 1836 times greater than that of a proton. Establish a mathematical relation to compare their masses.

Text Solution

Verified by Experts

Given, `(e)/(m_(e))=1836xx(e)/(m_(p))`, However the charge on 1 electron is the same as that of 1 proton.
`therefore (1)/(m_(e))=(1836)/(m_(p))`
or, `m_(p)=1836xxm_(e)`.
Hence, a proton is 1836 times heavier than an electron.
