The Attempt at a Solution



I thought it's D
but the correct answer is A.
I can't get it..
 
Physics news on Phys.org
An alpha particle consists of 2 protons and 2 neutrons, which are of equal mass (well, very nearly, anyway).
 
wow... silly me.
Thank you!
 
Alpha particle (in the past aka "alpha radiation") is the common name for the helium nucleus.
