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 = $$6 \times 10^{24}$$ kg]

A

$$4.24 \times 10^3$$ s

B

$$3.33 \times 10^2$$ s

C

$$1.33 \times 10^3$$ s

D

$$4.24 \times 10^2$$ s
