1.	Two small satellites move in circular orbits around the earth, at distances r and r + Delta r from the centre of the earth. Their time periods of rotation are T and T + Delta T. (Delta r lt lt r, Delta T lt lt T).
Answer» `DELTA T = (3)/(2)T(Delta R)/(r)` `Delta T = -(3)/(2)T(Delta r)/(r)` `Delta T = (2)/(3) T(Delta r)/(r)` `Delta T = T(Delta r)/(r)` ANSWER :A
