Question $3$

$5$ Points

A charged particle $($mass $=4\mathrm{.}0$ mg$,$ charge $=5\mathrm{.}0$ mC$)$ moves in a region where the only force on it is magnetic. What is the magnitude of the acceleration of the particle at a point where the speed of the particle is $5\mathrm{.}0$ km$/$s$,$ the magnitude of the magnetic field is $8\mathrm{.}0$ mT$,$ and the angle between the direction of the magnetic field and the velocity of the particle is $60?$
