Answer:
ratio of velocity is 3:2
Step-by-step explanation:
given data
orbits A = 2.40 B
to find out
What is the ratio of the orbital velocities of two satellites
solution
we know here orbit velocity formula that is
V =

here V is velocity and G is gravitational constant and M is mass of earth and r is distance from object to center of earth
so we calculate it for B that is V1
V1 =
.........................2
here r is B
and
for orbit A velocity is V2
V2 =
so here r is 2.40 B
sop from equation 2 and 3

solve it we get


so ratio is 3:2
