Answer:
The magnitude of the magnetic field is 0.156 T.
Explanation:
Given that,
Speed of a proton,
Radius of the circular path, r = 0.2 m
When the proton enters in the circular path, the centripetal force is balanced by the magnetic force such that :
q is the charge on proton
Here,
So, the magnitude of the magnetic field is 0.156 T. Hence, this is the required solution.
