Answer:
Magnetic force,
Explanation:
It is given that,
Velocity of proton,
Angle between velocity and the magnetic field, θ = 53°
Magnetic field, B = 0.49 T
The mass of proton,
The charge on proton,
The magnitude of magnetic force is given by :
So, the magnitude of the magnetic force on the proton is . Hence, this is the required solution.
