Two satellites S 1 and S 2 revolve round a planet in the same direction in circular orbits. Their period of revolution are 1 hour and 8 hour respectively. The radius of S 1 is 10 4 km. The velocity of S 2 with respect to S 1 will be
Text Solution
Verified by ExpertsThe correct answer is:
A
T 2 r 3
= 
= 
r = 4 × 10 4 km
T = 
V 1 – V 2 = 
– 
= 2 π 
= π × 10 4 km/hr
