A
: l
B
3:1
C
9 : 1
D
1:1
Text Solution
Verified by ExpertsThe correct answer is:
A
The orbital velocity is given
where M is the mass of earth and r is the radius of the orbit of satellite.
The velocity of the satellite with mass m is
and the velocity of the satellite with mass 3m is
Hence, the ratio of the velocities is
