easy

A charge moving with velocity $v$ in $X$-direction is subjected to a field of magnetic induction in the negative $X$-direction. As a result, the charge will

Remain unaffected

Start moving in a circular path $Y-Z$ plane

Retard along $X$-axis

Move along a helical path around $X$-axis

(AIPMT-1993)

Solution

(a) $\overrightarrow {{F_m}} = q\,(\overrightarrow {v\,} \times \overrightarrow B )$
When the angle between $\overrightarrow {v\,} $ and $\overrightarrow B \,is\, 180^o, F_m = 0$

Physics

An electron is moving along the positive $X$-axis. You want to apply a magnetic field for a short time so that the electron may reverse its direction and move parallel to the negative $X$-axis. This can be done by applying the magnetic field along

easy

An electron moves along vertical line and away from the observer, then pattern of concentric circular magnetic field lines which are produced due to its motion

easy

The direction of magnetic force on the electron as shown in the diagram is along

easy

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.
