If a proton is projected in a direction perpendicular to a uniform magnetic field with velocity $v$ and an electron is projected along the lines of force, what will happen to proton and electron

A

The electron will travel along a circle with constant speed and the proton will move along a straight line

B

Proton will move in a circle with constant speed and there will be no effect on the motion of electron

C

There will not be any effect on the motion of electron and proton

D

The electron and proton both will follow the path of a parabola

Solution

(b) Maximum force will act on proton so it will move on a circular path. Force on electron will be zero because it is moving parallel to the field.

An electron enters with a velocity ${\rm{\vec v}},{{\rm{v}}_0}{\rm{\hat i}}$ into a cubical region (faces parallel to coordinate planes) in which there are uniform electric and magnetic fields. The orbit of the electron is found to spiral down inside the cube in plane parallel to the $\mathrm{xy}$ – plane. Suggest a configuration of fields $\mathrm{E}$ and $\mathrm{B}$ that can lead to it.
