Question

A satellite of mass m completes one revolution around the earth at a constant speed s and radius r. Which of the following statements are false?

science physics

Answer 1

Answer #1

Option D is false because the work done by the earth on the satellite is zero .

The reason behind the zero work done is that the angle between the displacement and centripetal force is 90 degree.

An object of mass m moves at a constant speed v in a circular path of radius r.

An object of mass m moves at a constant speed v in a circular path of radius r. The force required to produce the centripetal component of acceleration is called the centripetal force and is given by F=mv2/r. Newton's Law of Universal Gravitation is given by F=GMm/d2, where d is the distance between the centers of the two bodies of masses M and m, and G is a gravitational constant. The speed required for circular motion is v= √(GM/r). Use the...
