Question

38. Two satellites of the same mass are orbiting round the earth
at heights of R and 4R above the earth's surface: R being the
radius of the earth. Their kinetic energies are in the ratio of
(a) 4:1
(b) 3:2
(c) 4:3
(d) 5:2​

Answer 1

Answer:

The answer is option D. The procedure is in the pic. Hope this helps!!

Answer 2

Answer:

D

Explanation:

Kinetic energy formula:

K.E = 1/2*GM1M2/(R+h)

Apply the formula for both the equations as shown in my solution and you will get the answer.
