Charged Particle in a Magnetic Field

A proton (q = 1.6×10⁻¹⁹ C, m = 1.67×10⁻²⁷ kg) enters a 0.50 T field at 2.0×10⁶ m/s perpendicular to B.

(a)2 points

Calculate the magnetic force on the proton.

(b)2 points

Describe the resulting path and why.

(c)3 points

Calculate the radius of the circular path.
