The given question is incomplete. The complete question is as follows.
For your senior project, you would like to build a cyclotron that will accelerate protons to 10% of the speed of light. The largest vacuum chamber you can find is 60 cm in diameter.
What magnetic field strength will you need?
Explanation:
Formula for the strength of magnetic field is as follows.
B =
Here, m = mass of proton = kg
v = velocity = 10% of =
m/s
q = charge of proton =
r = radius = = 30 cm = 0.30 m (as 1 m = 100 cm)
Therefore, magnetic field will be calculated as follows.
B =
=
=
= 1.0437 T
Thus, we can conclude that magnetic field strength is 1.0437 T.
