Step 1

The expression for the first satellite’s orbital speed is,

Step 2

Here, R1 is the first satellite’s orbital radius, G is the gravitational constant and M is the planet’s mass about which the satellite is orbiting.

The expression for the second satellite’s orbital speed is,

Step 3

Here, R2 is the second satellite’s orbital radius.

Take the rati...
