answer this for me too please: A small particle with positive charge q $=+3\mathrm{.}75$ x $10^(-4)$ and mass m $=5\mathrm{.}00$ x $10^(-5)$ kg is moving in a region of uniform electric and magnetic fields. The magnetic field is B $=4\mathrm{.}00$ T in the $+$z$-$direction. The electric field is also in the $+$z$-$direction and has magnitude E $=60\mathrm{.}0$ N$/$C$.$ At time t $=0$ the particle is on the y$-$axis at y $=11\mathrm{.}00$ m and has velocity v $=30$ m$/$s in the $+$ x$-$direction. Neglect gravity. $($a$)$ What are the x$-,$ y$-,$ and z$-$coordinates of the particle at t $=0\mathrm{.}0200$s$?($b$)$ What is the speed of the particle at t $=0\mathrm{.}0200$s $?$
