How many times is a proton heavier than an electron ?

The proton is heavier than an electron by _______.

Suppose an electron and a proton are projected with equal kinetic energy, what will be the ratio of their linear momentums if the proton is 1830 times heavier than an electron?

A proton and an electron initially at rest are accelerated by the same potential difference. Assuming that a proton is 2000 times heavier than an' electron, what will be the relation between the de Broglie wavelength of the proton (lambda_(p)) and that of electron (lambda_(e)) ?
