# Two satellites of masses m1 and m2(m1> m2) are revolving round the earth in circular orbits of radii r1 and r2(r1> r2) respectively. Which of the following statements is true regarding their speeds v1 and v2v1?

A
v1 = v2
B
v1 > v2
C
v1 < v2
D
v1r1=v2r2
Solution
Verified by Toppr

#### The correct option is Cv1<v2consider a satellite revolving at a distance r from the earth.inward force is GMmr2and outward force is mv2requating both the expression for equilibrium.so v=√GMr.so to if r increses then v decrease.so best possible answer is option C.
