Question

2. An electron is released from rest between the plates from the surface of the negative plate Circle the correct answers to the following assuming that the electron has arrived at the positive plate. (4 pts) a) Did the potential energy of the electron increase, decrease, or stay the same? b) Did the kinetic energy of the electron increase, decrease, or stay the same? c) Did the total energy of the electron increase, decrease, or stay the same? d) Is the electric potential at the final location lower or higher than that of the initial position? 3. Now assume that the plates are pulled apart so that there is a larger separation between them (d increases). Choose the correct answers (3 pts) a) The electric field increases, decreases, or stays the same b) The electric potential difference between the plates increases, decreases, or stays the same c) Assuming we repeat the scenario described in 2, the electron's final velocity increases, decreases, or stays the same

Explanation / Answer

(3) ans

Electric field is inversely proportional to the distance

So the distance is increases

The electric field is decreases

The electric potential difference is directly proportional to distance b/w plates

The distance is increases the potential difference is also increase

(c) the velocity =>vd

The distance is increases the velocity is also increases
