Answer:
At top vertical componant of velocity is zero
Cases A and B are all correct.
In Case C, the GPE is incorrect.
(But then, the power and HP have been correctly calculated
from the incorrect value of GPE, so we can't gig you too bad.)
Answer:
The answer is B
Explanation:
This is the only statement that is opinionated, therefore it is the only claim.
Answer:
The distance from the positive plate at which the two pass each other is 0.0023 cm.
Explanation:
We need to find the acceleration of each particle first. Let's use the electric force equation.


<u>For the proton</u>




<u>For the electron</u>



Now we know that the plate separation is 4.26 cm or 0.0426 m. The travel distance of the proton plus the travel distance of the electron is 0.0426 m.

Both of them have an initial speed equal to zero. So we have:



With this time we can find the distance from the positive plate (x(p)).


Therefore, the distance from the positive plate at which the two pass each other is 0.0023 cm.
