What is the magnitude of the magnetic field?
A beam of protons traveling at 1.40km/h enters a uniform magnetic field, traveling perpendicular to the field. The beam exits the magnetic field, leaving the field in a direction perpendicular to its original direction (the figure ). The beam travels a distance of 1.40 cm while in the field.
a) What is the magnitude of the magnetic field?
I apologize, the proton travels at 1.40 km/s instead of km/h
mass of proton = 1.67×10^-27 Kg
Force = BQV
Force = mV²/r
2πr = 1.4×10^-2
r = 2.228169203×10^-3 m
V = 1.4 Km/h = 0.3888888889 m/s
BQV = mV²/r
B(1.6×10^-19)(0.3888888889) = (1.67×10^-27)(0.3888888889)²/(2.228169203×10^-3)
B = 1.745329252×10^-6 T
