Answer:
d) 0 V
Explanation:
It can be showed that the potential due to a point charge q, to a distance d from the charge, can be expressed as follows:
where k = 
As the potential is an scalar, and is linear with the charge, we can apply the superposition principle, which means that we can find the potential due to one of the charges, as if the other were not present.
By symmetry, all four charges are at the same distance from the center, so we can write the total potential, as follows:
where d, is the semi-diagonal of the square, that we can find applying Pythagorean theorem, as follows:
Replacing by the values in (1) we have:
which is equal to the option d).
The potential energy of the monkey at the given position is 600.9 J.
<h3>What is potential energy?</h3>
Potential energy is the energy stored in a body that depends upon the relative position of various parts of the body.
It increases with increase in the height of the object above the ground level.

Potential energy of the monkey</h3>
The potential energy of the monkey is calculated as follows;
P.E = mgh
P.E = mg (L sin43)
where;
- m is mass of the monkey, given as 16.9 kg
- g is acceleration due to gravity, given as 9.8 m/s²
- L is length of the vine given as 5.32 m
Substitute the given parameters and solve potential energy of the monkey
P.E = (16.9)(9.8)( 5.32 x sin 43)
P.E = 600.9 J
Thus, the potential energy of the monkey at the given position is 600.9 J.

The energy in wind CAME from radiant energy originally, but it isn't
radiant energy any more. It's the energy in the mass of moving air,
and that's KINETIC energy.
You could move the turbine blades with stones or pingpong balls,
push the blades with your hands, or shoot water at them from a hose.
In any case, you'd have moving mass with kinetic energy transfer that
energy to the turbine. A moving mass of air does the same thing.
