A uniform magnetic field exists in the plane of paper Electron Proton ...
The force on charge "q" kept in a uniform magnetic field "B" is given by, F = q (v × B). Let i,j,k be the unit vectors along x,y,z axes respectively. Now for both proton and electron B = Bj
• For the proton, v = vi
F = q (vi × Bj)
= qvB (-k) (since i × j = -k)
• For the electron, v = v(-i)
F = (-q)(v(-i) × Bj)
= -(qvB) k (since -i × j = k)
= qvB (-k)
So, the forces acting on proton and electron are both same in magnitude and direction. Also, the force is into the plane of paper (or) -ve z direction.
