Answer:
The orbital speed of this second satellite is 5195.16 m/s.
Explanation:
Given that,
Orbital radius of first satellite
Orbital radius of second satellite
Mass of first satellite
Mass of second satellite
Orbital speed of first satellite = 4800 m/s
We need to calculate the orbital speed of this second satellite
Using formula of orbital speed
From this relation,
Now,
Put the value into the formula
Hence, The orbital speed of this second satellite is 5195.16 m/s.
