The equation for the speed of an object in circular orbit is V;
What does m represent in this equation?
a. the mass of the sun
b. the mass of Earth
c. the mass of the central object
d. the mass of the orbiting object
Please select the best answer from the choices provided

Answer 1

The equation for the speed of an object in circular orbit is V; here, m represents the mass of the orbiting object in the equation.

Answer: Option D

Explanation:

The below equation tells us about the orbital velocity of the objects moving in circular motion on the orbital path, where m is considered to be the mass of the orbiting object. The orbital velocity is the property of the orbiting body which has the formula as ,

`v=\sqrt{(G M)/(r)}`

Where, G is the gravitational constant and M is the mass of the body which is orbiting, with r is the radius of the circle which is taken up for the circular motion during the orbital motion.
