Question

1) critical velocity does not depend on the mass of the satellite.​

Answer 1

Answer:

Critical velocity of the satellite is inversely proportional to the square root of the radius of its orbit. The equation does not contain the term, 'm' which shows that the critical velocity is independent of the mass of the satellite.

Answer 2

Yes,it is true that the critical velocity doesn't depend on the mass of the satellite.

• The critical velocity of a satellite is the minimum required velocity to put that satellite in a particular orbit.

• The mathematical expression of the critical velocity of a satellite is :

Critical velocity = √{GM/(R+h)}

G = gravitational force

M = mass of the earth

R = radius of the earth

h = height of the satelite from the surface of the earth

• Now,the mass of the satellite is not mentioned in the above mathematical expression.

• So,we can say that the critical velocity of a satellite is not dependent on the mass of the satellite.
