Homework Statement
could you help me for the question b?
Homework Equations
E = mc^2
The Attempt at a Solution
the mass of the alpha particle is 0.66466 x 10^-26 kg >> 4.022 u
put it into the equation, so
E = 4.022 x c x c = 3.615 x 10^17 eV >> 0.0579 joule
my answer is that, but my teacher answer is 1.89x10^-13 joule..
which one is true? can you show me where's my wrong?
