Aristotle and Ptolemy said that earth is in the center and all other planets move in a circular motion around Earth.
Aristotle from Classic Greece and Ptolemy from Roman Egypt agreed on three facts:
- Earth and other celestial bodies are spherical in shape.
- Earth is in the center and all other celestial bodies revolve around it.
- The other planets orbit in a circular path.
This model of the solar system with Earth in the center is called as Geocentric model.
Therefore, Aristotle and Ptolemy said that earth is in the center and all other planets move in a circular motion around Earth.

Explanation :
It is given that,
Side of square,
It is given that, the potential at point c is equal to zero.
So, potential at point a due to and is given as:
where,
So, (Since, is negative)
Hence, the potential at a due to and is equal to 0 V.
Answer:
Option A is correct.
Explanation:
In the given triangle , x is the base and 14 is the hypotenuse for angle 33°.
cos 33 = base / hypotenuse
Putting the given values
cos 33 = x / 14
.84 = x / 14
x = .84 x 14
= 11.7
Option A is correct.
