Ответ:
A magnetic force of 58.22 fN is acting on the proton
Explanation:
The magnetic force of a particle moving through a magnetic field B is defined from the Lorentz Force Law:
F=q*v*B*sin()
q ⇒ charge ⇒ proton electric charge ⇒ 1.6021766208* C ≈ 1.6* C
v ⇒ velocity ⇒ 26.7% of the speed of light ⇒ 0.267* 299 792 458 m/s ≈ 0.267*3* m/s
B ⇒ magnetic field ⇒ 0.00649 T
⇒ angle in degrees between the velocity and the magnetic field ⇒ 135°
F = 1.6* C * 0.267*3* m/s * 0.00649 T * sin(135°)
T = N*s/C*m
C* (m/s) * T= C* (m/s) * (N*s/C*m) = N (Newton, force unit)
sin(135°) = 0.70710678118 ≈ 0.7
F = 1.6* C * 0.267*3* m/s * 0.00649 T * 0.7
F = 58.22* N
F = 58.22 fN
