27 A planet is moving in an elliptical orbit around the sun If T V E and L stand respectively for its kinetic energy gravitational potential energty total energy and magnitude of angular momentum about the centre which of the following is correct 1 T is conserved 2 V is always positive 3 E is always negative 4 L is conserved but direction of vector L changes continuously
