At t $=0,$ a particle with charge $+2\mathrm{.}0/$C and mass $1\mathrm{.}5$ x$10-8$ kg passes through the origin of acoordinate system, and is moving in the ry$-$plane with speed $900$ m$/$s at an angle $0=25\backslash$deg above the I$-$axis. There is a uniform magnetic field with magnitude $0\mathrm{.}08$ Tesla pointing in the $+*$ direction, asxN$-($a$)$ Find the magnitude of the force exerted on this particle.$($b$)$ What is the direction of this magnetic force? Make reference to the coordinate system to answer this.$($c$)$ At what time after t $=0$ will the particle next intersect the $-$axis? $($Hint: Think about the motionof the particle in the yz$-$plane. What is its period?$)($d$)$ Where along the x$-$axis will the intersection in part $($c$)$ occur?
