The answer is 1.56 x 10^13You plan to build a large, cheap cyclotron using the Earth's magnetic fields(1x10^-4 T) and orbiting just above the Earth's atmosphere (radius 5.7 x10 ^6 m) What energy, in volts, should protons be given to just circle the earth? q= 1.6 x10^-19 C, m= 1.67x10^-27
I can't get the answer.
Fm = F centripetal Force
qvB = mv^2/r
v= rqB/m
Calculate energy
KE = 1/2 mv^2
I put in v = rqB/m
KE= 1/2 (rqB)^2/m
I plug in all the #, but still can't the answer
please help, thanks so much!
