A small demo Van de Graaf Generator can accelerate charges with a potential difference of 3.0 x 10^5 V. How fast can a proton move with the aid of this device?
q: charge
d: distance
V: voltage
E: Electrostatic field strength
Mass of Proton [According to my formula sheet]: 1.67 x 10^-27 kg
Elementary charge: 1.60 x 10^-19 C
2. F[electrostatic]=qE
F=ma
E = V/d
3. I tried using the formula F=qE to calculate force, but I only have the potential difference with no distance. I'm guessing you have to imput the value you get from F[electrostatic] into the formula F = ma, but I really don't know how to do it given only voltage.
