$B > \frac{qd}{mv}$
$B < \frac{mv}{qd}$
$B < \frac{qd}{mv}$
$B > \frac{mv}{qd}$
A charged particle moves with velocity $v$ in a uniform magnetic field $\overrightarrow B $. The magnetic force experienced by the particle is
A proton, a deuteron and an $\alpha$ particle are moving with same momentum in a uniform magnetic field. The ratio of magnetic forces acting on them is.......... and their speed is.................. in the ratio.
If a particle of charge ${10^{ - 12}}\,coulomb$ moving along the $\hat x - $ direction with a velocity ${10^5}\,m/s$ experiences a force of ${10^{ - 10}}\,newton$ in $\hat y - $ direction due to magnetic field, then the minimum magnetic field is
An electron enters a magnetic field whose direction is perpendicular to the velocity of the electron. Then
The radius of circular path of an electron when subjected to a perpendicular magnetic field is
