A proton is released from rest at the positive plate of a parallel-plate capacitor. It crosses the capacitor and reaches the negative plate with a speed of 50,000 m/s. What will be the proton's final speed if the experiment is repeated with double the amount of charge on each capacitor?
I seem to be stuck on this one. I initially tried to use
1/2 m[tex]^{}_{i}[/tex]v[tex]^{2}[/tex] + V[tex]^{}_{i}[/tex]q = 1/2 m[tex]^{}_{f}[/tex]v[tex]^{2}[/tex] + V[tex]^{}_{f}[/tex]q
but i ran into a wall. Help please.
