Question

Two satellites of earth, S₁ and S₂ are moving in the same orbit. The
mass of S₁ is four times the mass of S₂. Which one of the
following statements is true?
(a) The potential energies of earth satellites in the two cases are equal
(b) S₁ and S₂ are moving with the same speed
(c) The kinetic energies of the two satellites are equal
(d) The time period of S₁ is four times that of S₂

Answer 1

Answer:

The right answer is b

Explanation:

The formula for potential energy is mgh. This formula is dependent on mass, so it won't be equal.

The formula for kinetic energy is 1/2mv^2

this is also dependent on the mass of the object.so it can't be equal.

time period can differ
