1.	Two satellite A and B revolve round the earth in circular orbits at heights R_(A) and R_(B) respectively from the surface of the earth. If the radius of the earth is R_(E), the ratio of magnitude of the velocities fo the satellites is
Answer» `SQRT((R_(B) + R_(E))/(R_(A) + R_(E)))` `(R_(B) + R_(E))/(R_(A) + R_(E))` `sqrt((R_(B))/(R_(A)))` `(R_(B))/(R_(A))` ANSWER :A
