Question

Two satellites A and B of masses 200 kg and 400 kg are revolving round the earth at height of 600 km and 1600 $k m$ respectively. If $T_A$ and $T_B$ are the time periods of $A$ and $B$ respectively then the value of $T_B-T_A$ :

[Given : radius of earth $=6400 \mathrm{~km}$, mass of earth $=6 \times 10^{24} \mathrm{~kg}$ ]

Select the correct option:

A

$1.33 \times 10^3 \mathrm{~s}$

B

$3.33 \times 10^2 \mathrm{~s}$

C

$4.24 \times 10^3 \mathrm{~s}$

D

$4.24 \times 10^2 s$

✓ Correct! Well done.
