Answer 1

The two subatomic particles that have relatively the same mass are neutrons and protones.

They both have a mass of 1 amu (atomic mass unit) which is equal to 1.67x10-27 kg. They also have the same diameter (1.7x10-15m). The difference between them is that protomes ar positively charged but neutrons have no charge.
