Question
An electron moving with a velocity of 107 m/s enters a uniform magnetic field of 1 T along a direction parallel to the field. What would be its trajectory?
Solution
The electron will move undeflected in a straight line as, the particle is travelling in a direction paralle to the direction of magnetic field.
F = qvB sin θ [ θ = 0 ]
F = qvB sin θ [ θ = 0 ]
