i1.8kev = 2.8839E-16 J i don't really know how to do the velocity thing would it be v^2= ke/.5m

sorry i really don't understand the other ways

or could you use q/m = .5(velocity^2) / voltage

`i am doing magnetism. i think we are just using trig formulas. what i have gotten so far is A->q/m =2v / B^2 R^2 2(7.28*10^8)/ (0.038^2) R^2 then use r =mv/qb to get r B-> 1.6*10^-19 i just don't know how to actually get r

I don't really know to be honest. I am quiet lost on how to do it. don't even really know how to start it

2(7.28E+08) / (0.038^2) R^2 i don't know how to get r
