The Large Hadron Collider, or LHC, to be completed later this year, accelerates protons around a nearly circular track of circumference 26.66 km to a momentum of up to 3.74e-15 kg m/s. However, when the collider is being "ramped up", its momentum may be considerably less.(a) What is the strength of the magnetic field required to keep the protons on the track when the momentum is 2.30e-15 kg
m/s?
T
(b) The LHC can also accelerate fully ionized (no electrons) atoms of Lead (Pb). For the same magnetic field as in part (a), what is the momentum of the lead ions?
kg m/s
