Let
M = the mass of the planet
n = the mass of the satellite.
r = the radius of the planet
When the satellite is at a distance r from the surface of the planet, the distance between the centers of the two masses is 2r.
The gravitational force between them is
where
G = the gravitational constant.
When the satellite is on the surface of the planet, the distance between the two masses is r.

Answer:
Given :
The light rays in the incident ray originate at 20º from the surface.
To Find :
The angle for the incident ray.
Solution :
We know angle of incidence is measured from perpendicular to the surface .
So,
Now, we know by law of reflection :
Angle of reflection = Angle of incident
Therefore, the angle of incident and reflection is 70° each.
