Answer:
The radius of orbit=
Explanation:
We are given that
Orbital speed=
m/s
We have to find the radius of orbit of spacecraft.
We know that
Gravitational constant=
Mass of earth=
Orbital speed=
Where G= Gravitational constant
M=Mass of earth
r=Radius of orbit
Substitute the values in the formula

Squaring on both sides



Hence, the radius of orbit=
The correct answer is C. more mass and less distance between two objects.
