Homework Statement
A small object with mass m, charge q, and initial speedv0 = 5.00×10^3 m/s is projected into a uniform electric field between two parallel metal plates of length 26.0 cm (Figure 1) .The electric field between the plates is directed downward and has magnitude E = 700 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 = 1.15 cm from its original direction of motion and reaches a collecting plate that is 56.0 cm from the edge of the parallel plates. Ignore gravity and air resistance.
Homework Equations
E=F/q
xf=xi+vi*t+(1/2)at^2
The Attempt at a Solution
Since gravity and air resistance air are not factors, I thought the only thing affecting the motion of the object is the electric field. Using the horizontal velocity, I calculated the time that the object was between the plates. Then, using that and the second equation I calculated the vertical acceleration of the object. From there, I expanded the first equation into E=(m*a)/q and plugged in the acceleration and given electric field and solved for q/m
