Two satellites of masses `m_(1)andm_(2)(m_(1)gtm_(2))` are moving around the earth in orbits of radii `r_(1)andr_(2)(r_(1)gtr_(2))`. Which one of the following statements about their velocities is correct?

A

`v_(1) =v_(2)`

B

`v_(1) lt v_(2)`

C

`v_(1)gtv_(2)`

D

`(v_(1))/(r_(1)) =(v_(2))/(r_(2))`

Text Solution

Verified by Experts

The correct Answer is:
B

`v =sqrt((GM)/(r))" it "r_(1) gtr_(2) " then " v_(1) lt v_(2)`
