Infer what will happen to the capacitance, charge, and potential difference in the respective capacitors when their size, potential difference, charge will change?

A proton with a speed of 2.0x10^5m/s enters a region of space in which source charges have created an electric field potential "v"; What is the proton speed after it move through a potential difference of 100volts.

- What will be the final speed if the proton replace an electron.

Mass of Proton = 1.67x10^-27kg

Mass of Electron = 9.1x10^-30kg
