It would have to be a solid so the answer would be A.
I'm not completely sure, but I think it's 3.4 newtons. I hope you get it correct.
The potential energy of the model will be the greatest at point C while it will be the least at point E. Option B and D are correct.
<h3>
What is potential energy?</h3>
The potential energy of an object is due to its position. It can be given as the formula,

Where,
- potential energy
- mass
- gravitation acceleration
- height
From the formula since the mass and gravitation acceleration is constant, the potential energy of the model will depend upon the height only.
The potential energy will be greatest at point C because the relative position of the ball is the highest from the earth.
The potential energy will be lowest at point E because the height of the ball is the least in this position.
Therefore, the potential energy of the model will be the greatest at point C while it will be the least at point E.

A circle is just a very very very special kind of ellipse.
So the correct choice is ' A ' .
