a A proton moving in the +x direction with velocity v, = v B, could be any value

Question

a A proton moving in the +x direction with velocity v, = v B, could be any value, By-F / (e v), B, = 0 experiences a magnetic force F = in the +y direction. Explain what you can and cannot infer about from th information. b, could be any value, By = 0, Bz = f/ (e r) B, could be any value, By--f / e vi), 8, 0 Bx could be any value, By-0, Bz--6/ (e vi) (b) In terms of F, what would be the force on a proton in the same field moving with velocity (c) What would be the force on an electron In the same fleld moving with veloclty v 1? (Use the following as necessary: F.)

Explanation / Answer

(a) Option D) is correct.

Using Lorentz force, F = q(v x B)

From here B will be in -z-axis. Bz = -F/ve

(b) F = e(-vii x -Bz) = e*vi*B (-j)

(c) F = -e(vii x -Bz) = e*vi*B (-j)
