Answer:
The magnetic field strength, B is 1.043 T.
Explanation:
The expression for the magnetic field is as follows as;

Here, m is the mass, r is the radius, v is the speed, q is the charge and B is the magnetic field.
According to the given problem, 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.
v= 10% of the speed of the light




r=0.30 m
Calculate the magnetic field strength.

Put
,
,
and r=0.30 m.

B= 1.043 T
Therefore, the magnetic field strength is 1.043 T.
Momentum = (mass) x (speed)
Momentum = (12,000 kg) x (40 m/s)
Momentum = (12,000 x 40) kg-m/s
<em>Momentum = 480,000 kg-m/s </em>
