A satellite of mass m is revolving around the Earth at radius R with time period T. Which of The following statement is NOT TRUE?
- The kinetic energy is \(\frac{1}{4} \mathrm{mgR}\) at a height equal to radius of the Earth R
- If another satellite of mass 4m is also revolving in the parking orbit, ratio of their time-period is 1 : 4
- If the earth suddenly shrinks to half its size without any change in mass, its time-period will remain the same
- If the radius of the orbit is increased to 4R, its time-period will increase to 8T
Answer
(B) If another satellite of mass 4m is also revolving in the parking orbit, ratio of their time-period is 1 : 4
