Suppose the resonant frequency is f = 1.47×1010 s−1; that is, the electron period of revolution is T = 6.80×10-11 s. What is the corresponding strength of the magnetic field?
Homework Equations
qvb=mv2/r
qb=mv/r
The Attempt at a Solution
1.6E-19*b=9.1E-31*v/r
I understand the general idea, to figure out b, but I don't understand how to figure out Velocity or Radius from the frequency/period.

When they give the period, that is the period of what? In other words, if the period is 6.80×10-11 s, what happens every 6.80×10-11 seconds? Once you answer that, you should be able to write down an equation relating T, r, and v. What do you get?
A magnetron electron field strength is a measure of the strength of the electromagnetic field generated by the electrons in a magnetron, which is a type of vacuum tube used to generate microwaves.
Magnetron electron field strength is typically measured using a gaussmeter, which measures the strength of a magnetic field in units of gauss. However, it can also be calculated using the current and voltage applied to the magnetron.
Magnetron electron field strength is important because it directly affects the performance of a magnetron. A strong electron field is necessary to produce high-powered microwaves, which are used in a variety of applications such as cooking and radar systems.
The main factors that can affect magnetron electron field strength are the current and voltage applied to the magnetron, the design and construction of the magnetron, and any external magnetic fields that may be present.
Yes, magnetron electron field strength can be adjusted by changing the current and voltage applied to the magnetron. However, this should only be done by trained professionals as incorrect adjustments can damage the magnetron and affect its performance.
