Two answers are required for this problem.
A proton is accelerated through apotential difference of 1,000 V. After leaving the region of the electric field, the proton enters a magnetic field and is observedto be on a curved path of radius 5.0 cm. Assuming the magneticfield is perpendicular to the path of the proton,
a. What is the magnitude of the magnetic field?
b. What is the frequency of there volution?
