Two satellites of masses `m_(1) and m_(2)(m_(1) gt m_(2))` are revolving around the earth in circular orbits of radius `r_(1) and r_(2)(r_(1) gt r_(2))` respectively, which of the following is true regarding their speeds `V_(1) and V_(2)` ?

Options

A. `V_(1)=V_(2)`
B. `V_(1) lt V_(2)`
C. `V_(1) gt V_(2)`
D. `(V_(1))/(r_(1))=(V_(2))/(r_(2))`

Answer

B

Explanation

Orbital velocity `V_(0)= sqrt((GM)/(r )) rArr V_(0) prop (1)/(sqrt(r ))`
So the correct choice is (b).
