OriginalQuestion Thomson Charge to Mass Suppose we have an electron moving perpendicular to a B-field along a circular path of radius 17 cm. If imposition of an E-field of 17.8 kV/m makes the path straight, what is the value of B? Bfield= ErrorAnalysis Suppose our E-field measurement has an uncertainty of 0.25 kV/m and our radius of curvature measurement has an uncertainty of 0.6 cm. What is the total uncertainty associated with the magnetic field we just calculated? dBtot=
