Asatellite travels at orbital speed v around a planet of mass m. if the planet had half as much mass, what would be the new orbital speed of the satellite?

v/2

v

v

v/2

2v

Explanation:

To solve the problem, we can equate the gravitational force that keeps the satellite in orbit with the centripetal force:

where

G is the gravitational constant

M is the mass of the planet

m is the mass of the satellite

v is the orbital speed of the satellite

r is the distance of the satellite from the planet's centre

Solving the formula for v,

If the planet has half of the initial mass: , the new orbital speed of the satellite will be

what is the question because that is not a question.

explanation:

v=uf/(u-f)
