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 km 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 km, mass of earth = 6 $\times$ 10²⁴ kg]

1.33 $\times$ 10³ s

4.24 $\times$ 10² s

3.33 $\times$ 10² s

4.24 $\times$ 10³ s
