Question \( A \) planet is moving in an elliptical orbit. If \( T, U, E \) and \( L \) are its kinetic energy, potential energy, total energy and magnitude of angular momentum respectively, then which of the following statement is true:-
(A) \( T \) is conserved
(B) \( U \) is always positive
(C) \( E \) is always negative
(D) \( L \) is conserved but the direction of vector \( \vec{L} \) will continuously changeš²PW App Link - https://bit.ly/YTAI_PWAP šPW Website - https://www.pw.live
