Answer:[tex]v=\sqrt{\frac{Gm}{r}}[/tex]

Explanation:

Given

Orbital speed is v

Mass of planet is m

Radius of circular orbit is r

suppose M is the mas of satellite then centripetal force on satellite is equal to the Gravitational Pull.

[tex]\frac{Mv^2}{r}=\frac{GMm}{r^2}[/tex]

where G=gravitational constant

thus on solving we get

[tex]v=\sqrt{\frac{Gm}{r}}[/tex]

The orbital speed v of a satellite in a circular orbit of radius r around a planet of mass m should be v = √Gm/r.

Calculation of the orbital speed:

Since

Orbital speed is v

Mass of planet is m

The radius of the circular orbit is r

Here we assume M is the mass of the satellite so the centripetal force on the satellite should be equivalent to the Gravitational Pull.

So,

Mv^2 /r = GMm/r^2

Here

G=gravitational constant

So, v = √Gm/r.
