Problem

A charged track curves with radius of curvature r=33.4 mr = 33.4\,\mathrm{m} in a solenoid field of B=1.5 TB = 1.5\,\mathrm{T}, using the same curvature relation p [GeV/c]=0.2998 B [T] r [m]p\,[\mathrm{GeV}/c] = 0.2998\,B\,[\mathrm{T}]\,r\,[\mathrm{m}]. ((a)) Find the transverse momentum of the track. ((b)) If the tracker's momentum resolution is quoted as about 1%1\%, state the absolute momentum uncertainty in MeV/c\mathrm{MeV}/c.
