If a second satellite of mass "2M" is to be placed in the similar orbit, the second satellite must have a velocity which is:
a) Half the velocity of the first satellite
b) The similar as the velocity of the first satellite
c) Twice the velocity of the first satellite
d) Four times the velocity of the first satellite
