A small object with mass $m,$ charge $q,$ and initial speed $v_0=6\mathrm{.}00{10}^3\frac{m}{s}$ is projected into a uniform electric field between two parallel metal plates of length $26\mathrm{.}0cm($Figure $1).$ The electric field between the plates is directed downward and has magnitude $E=600\frac{N}{C}.$ Assume that the field is zero outside the region between the plates. The separation between the plates is large enough for the object to pass between the plates without hitting the lower plate. After passing through the field region, the object is deflected downward a vertical distance $d=1\mathrm{.}45cm$ from its original direction of motion and reaches a collecting plate that is $56\mathrm{.}0cm$ from the edge of the parallel plates. Ignore gravity and air resistance.

Part A

Calculate the object's charge$-$to$-$mass ratio, $\frac{q}{m}.$

$\frac{q}{m}=\frac{C}{k}g$
