Pls help quick!

A satellite orbiting Earth at an orbital radius r has a velocity v. Which represents the velocity if the satellite is moved to an orbital radius of 5r?(1 point)

5v

v / √5

Step-by-step explanation:

Solution:-

- We have a satellite of mass ( m ) that orbits the earth of mass ( M ). The radius of orbit is ( r ) : center of earth - to - center of satellite radial distance.

- The satellite orbits the Earth with constant tangent velocity ( v ). The velocity  ( v ) is a function of massive body ( M ) about which the smaller body orbits and orbital radius ( r ).

- The formulation is given by:

Where,

          G: The universal gravitational constant

- We are to compare the orbital speeds by changing some of the parameters in the above relation.

- The effect on the orbital speed ( v_orbit ) by increasing the orbital radius to ( 5r ) can be evaluated using the given relation. Such that:

- Now take the ratio of initial orbital speed to the increased orbital radius ( 5r ):
