Answer:
(D) any of these objects can be used as long as all points on the object lie farther away from the lens than the focal length of the lens.
Points lying between the focal point and the lens will be erect and will not form an object visible on a screen.
To check progress and direction
The speed of the proton is
Data;
- potential difference (A) = 3500V
- potential difference (B) = -1500V
<h3>Velocity of The Proton</h3>
The work done to move through a potential velocity 'v' is q
The potential difference 'v' is the difference between A and B
But the work is converted into kinetic energy of proton.
Let's substitute the values and solve for the velocity
The speed of the proton is

Answer:
Potential refers to stored energy while kinetic is energy in motion. All energy, whether potential or kinetic, is measured in Joules (J).
