Okay, so for this problem, it's asking the mass of a bare alpha particle.
00:07
And so without electrons and mega electron volts per c squared units.
00:13
And so how i approached this was i said, okay, well, bear alpha particle has two neutrons and two protons, just sort of from reading the text.
00:21
I got the information as i was reading talks about how you also have to consider that you have to add, subtract the binding energy and in the text it says it's the binding energy.
00:33
I'm not actually sure the it's ebinding is the common way of writing it, but ebinding is 28 .3 mega electron volts.
00:47
So then basically what you'd need to do is add this up, sorry, add up the mass of the bare nucleons and and subtract the binding energy.
01:00
And you can neglect the binding energy of the electrons, because as it tells you in the text, it's negligible.
01:13
It's on the electron volt scale, not for c squared...
