1.	For a planet moving around the Sun in an elliptical orbit of semimajor and semiminor axes a and b respectively and Time period T.For this situation which one of the following statements is correct?
Answer» The torque acting on the planet about the Sun in non-zero The angular momentum of the planet about the Sun is CONSTANT The planet moves with a constant SPEED around the Sun The areal velocity is `piab//T` Solution :For a planet MOVING around the Sun, the angular momentum of the planet is conserved.
