apply in cyclotron
apply centripetal force = magnetic force
i.e mv^2/r = qvB,
where m = mass o the charged particle
v = velocity, r = radius ,
q = charge = 1.6*10^-19 C
B = magnetic field
so now , r = mv/qB
so as r = D/2 = 0.0361/2 = 0.01805 m
so
q/m = v/Br
q/m = 191/(0.0691 * 0.01805)
q/m = 1.53 e 5 C/ kg
