Consider the following statements regarding a charged particle in a magnetic field . Which of the statements are true :
Starting with zero velocity, it accelerates in a direction perpendicular to the magnetic field.
Direction of deflecting force on the moving charged particle is perpendicular to its velocity.
Only the component of magnetic field perpendicular to the direction of motion of the charged particle is effective in deflecting it.
Both $(B)$ and $(C)$
An electron moving with a uniform velocity along the positive $x$-direction enters a magnetic field directed along the positive $y$-direction. The force on the electron is directed along
Give expression for the force on a current carrying conductor in a magnetic field.
A particle of mass $m = 1.67 \times 10^{-27}\, kg$ and charge $q = 1.6 \times 10^{-19} \, C$ enters a region of uniform magnetic field of strength $1$ $tesla$ along the direction shown in the figure. the radius of the circular portion of the path is :-
If a proton enters perpendicularly a magnetic field with velocity $v$, then time period of revolution is $T$. If proton enters with velocity $2 v$, then time period will be
A very long straight wire carries a current $I$. At the instant when a charge $ + Q$ at point $P$ has velocity $\overrightarrow V $, as shown, the force on the charge is
