Asatellite weighs 10,000n on earth. if the satellite orbits at a distance of 1 earth radii (twice as far from the center of the earth), what will it weigh? a) 2,500n b) 5,000n c) 10,000n d) 20,000n

Answer

2500 N

Explanation

If a satellite ways 10000 N at the surface of the earth it means there is zero distance between the rocket and the surface of the earth. However,when the satellite will start rising from the surface of the earth and the distance will reach equal to the radius of the earth, it means that distance is around double of the distance from the earth surface.

So when the distance has become double, the weight will become 1/4th.

                                    1/4 x 10000 N = 2500 N

So, 2500 N is the right answer

Hope it helps!

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
