Question

In N14 if mass attributed to electrons were doubled
& the mass attributed to protons were halved, the
atomic mass would become approximately :-
(1) Halved
(2) Doubled
(3) Reduced by 25%
(4) Remain same​

Answer 1

(3) Reduced by 25%

This is because mass of electron is negligible.

And only the mass of neutron and proton are taken into account, so they bothake half half of the masses.

Now if one half is halfed we get 1/4 which is 50% less than the total mass of proton and 25% less than total mass of both neutron and proton.
