a particle having mass of 10^-30 kg and a charge of 10^-18 coulombs and an energy of 5000eV is fired into an electric field produced by two parallel plates. the electric field between the plates is 10V/m and the length of the plates is 0.4 m, how much deflection d, will the charge experience as it traverses the plates?
d is the distance from the center of the path between the two charged plates
electric field E = kq/r^2 where k = 9*10^9, q is the charge, r is the radius
The Attempt at a Solution
i am completely lost on this one as i don't know how to implement the given energy of the particle, i am pretty sure the electric field equation will be used but i am sure that there are others. should i assume d = r? in other words, solve for r?
do i sub in 10V/m for E, 10^-18 for q? what about r?
i need another equation that factors in energy, mass and the length of the plates, i don't think i have come across such an equation yet? gauss-related???
any help appreciated, i wish i could give more but that is as much as i have thought of thus far...
