1.	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 TA and TB are the time periods of A and B respectively then the value of TB−TA is: [Given : Radius of earth=6400 km, Mass of earth=6×1024 kg]
Answer» 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 $T_{B} - T_{A}$ is: $[$ Given : Radius of earth $= 6400 km$ , Mass of earth $= 6 \times 10^{24} kg]$
