Homework Statement
A pair of oppositely charged, parallel plates are separated by a distance of 5.0 cm with a potential difference of 500 V between the plates. A proton is released from rest at the positive plate, and at the same time an electron is released at the negative plate. Neglect any interaction between the proton and the electron.
a. After what interval will their paths cross?
b. How fast will each particle be going when their paths cross?
c. At what time will the electron reach the opposite plate?
d. At what time will the proton reach the opposite plate?
Homework Equations
I seriously don't know there are soo many equations but these will probably do the job:
E=Fe/Q
E=k q/r2
Sum of all forces=ma
d=vit+1/2at2
The Attempt at a Solution
I don't know where to start. I honestly I tried using E=k q/r2 then find Fe with E=Fe/Q and use sum of all forces but then I took into account that both the positive plate and negative plate were acting on either proton or electron at the same time and from there I got completely lost
