Homework Statement
In the figure, a uniform, upward-pointing electric field E of magnitude 2.00×103 N/C has been set up between two horizontal plates by charging the lower plate positively and the upper plate negatively. The plates have length L = 4 cm and separation d = 2.00 cm. Electrons are shot between the plates from the left edge of the lower plate.
The first electron has the initial velocity v0, which makes an angle θ=45° with the lower plate and has a magnitude of 5.86×106 m/s. Will this electron strike one of the plates? If so, what is the horizontal distance from the left edge? If not enter the vertical position at which the particle leaves the space between the plates.
Homework Equations
I believe that the proper equations that one could use would be the following:
v[initial, y]^2 + (2*a*deltaY) = 0
acceleration = [eE]/[m]
v[initial,y] + (a*t) = 0
The Attempt at a Solution
I had to solve a similar problem like this, where the electron had actually hit one of the metal plates. However, I think that this time it is different and I don't necessarily know where to go from here. I tried to do what I had done for the other part, but the answers yielded incorrect results.
Any help at all is greatly encouraged.
