1.	A rigid body rotates with an angular momentum L. If its kinetic energy is halved, the angular momentum becomes,
Answer» L `(L)/(2)` 2L `(L)/(sqrt(2))` Solution :ANGULAR MOMENTUM, `L= sqrt(2mE_(K))` If `E_(K)` is halved `E_(K).= (E_(K))/(2)` New angular momentum, `L.= sqrt(2ME._(K))= sqrt((2mE_(K))/(2))` `L.= (L)/(2)`
