In the following question statement 1 represent Assertion and statemen

1.	In the following question statement 1 represent Assertion and statement 2 represents Reason .Statement 1 : In a uniform circularmotion the momentum of a particle does not change with time .Statement 2 : The kinetic energy of the particle remains constnat .Choose the correct statement of the following statements
Answer» Statement 1 is true and statement 2 is true and it EXPLAINS statement 1. Statement 1 is true and statement 2 is true and it does not explain statement 1. Statement 1 is true and statement 2 is FALSE. Statement 1 is false and statement 2 is true. Solution :The momentum changes with time sincethe DIRECTION ofvelocity vector CHANGE with time . But its velocity remains constant . So kinetic energy remainsconstant .
