Answer:
6.72 x 10⁻¹⁶ N
Explanation:
v = speed of the proton moving through the magnetic field = 7 km/s = 7000 m/s
B = magnitude of magnetic field in the region = 0.60 T
q = magnitude of charge on the proton = 1.6 x 10⁻¹⁹ C
θ = Angle of magnetic field with the velocity of proton = 90
F = magnitude of magnetic force
magnitude of magnetic force is given as
F = q v B Sinθ
F = (1.6 x 10⁻¹⁹) (7000) (0.60) Sin90
F = 6.72 x 10⁻¹⁶ N
