Question

What is the kinetic energy of the alpha particle when it reaches the other plate?

Answer 1

Answer:

here's ur answer mate

] THe alpha particle has a charge of 3.20×10-19 C.

2] So it will pick up energy of 3.20×10-19 C x 155 V

3] 1 C V = 1 J

4] By conservation of energy, the electrical potential energy turns into kinetic energy.

5] THe distance is irrelevant. As is the mass

6] Strictly speaking, accelerating a charge will release a photon, which will carry away some of the energy, but I think you are allowed to ignore that. But you could just note this at the bottom and try for extra credit...
