Two satellites of masses of m_(1) and m_(2)(m_(1)gtm_(2)) are revolving round the earth in circular orbits of radius r_(1) and r_(2)(r_(1)gtr_(2)) respectively. Which of the following statements is true regarding their speeds v_(1) and v_(2) ?

Assertion : Two satellites of mass m_(1)& m_(2)(m_(1) gt m_(2)) are going around the earth in orbit of raddi s r_(1) and r_(2)(r_(1) gt r_(2)) . Reason : They will have same velocity .

Two satellites A and B are revolving around the earth circular orbits of radius r_(1) and r_(2) respectively with r_(1) lt r_(2) . Plane of motion of the two are same. At position 1, A is given an impulse in the direction of velocity by firing a rocket so that it follows an elliptical path to meet B at position 2 as shown. A?t position 2, A is given another impluse so that velocities of A and B at 2 become equal and the move together. For any elliptical path of the satellite of the time period of revolution is given by Kepler's planetary law as T^(2)alpha r^(3) where a is semi major axis of the ellipse which is (r_(1)+r_(2))/(2) in this case. Also angular mopmentum of any satellite revolving around the Earth will remain a constant about EArth's centre as force of gravity on the satellite which keeps it in elliptical path is along its position vector relative to the earth centre. If the two have same mass

Two satellites A and B of masses m_(1) and m_(2)(m_(1)=2m_(2)) are moving in circular orbits of radii r_(1) and r_(2)(r_(1)=4r_(2)) , respectively, around the earth. If their periods are T_(A) and T_(B) , then the ratio T_(A)//T_(B) is
