Homework Equations
r=mv/qb
mv=sqrt(2*KE*m(alpha))
m(alpha)=6.64e-27 kg
The Attempt at a Solution
i was just wondering how to get the answer (7.6e-4 m). i get path curving down, and do
r=sqrt(2*1e3eV*6.64e-27kg*1.6e-19J/eV)/(q*B)
=15.18e-4m
so to get the right answer i would have to divide this by 2..why is this?? i used the right equation but am I doing something wrong?
