Question

Imagine a particle that has three times the mass of the electron. All other quantities given above remain the same. What is the ratio of the kinetic energy Kheavy that this heavy particle would have when it reaches the upper plate to the kinetic energy Ke that the electron would have? That is, what is KheavyKe? g

Answer 1

Answer:

The only parameter that changes is mass m

It is only necessary to calculate the ratio Eh/Ee

$m_{h}=3m_{e}\\E_{h}=\frac{3m_{e}v^{2}}{2}\\E_{e}=\frac{m_{e}v^{2}}{2}\\\frac{E{h}}{E{e}}=3$

The kinetic energy of the heavy paricle is three times the kinetic energy of an electron
