In the following question statement 1 represent Assertion and statement 2 represents Reason .
Statement 1 : In a uniform circular motion 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

Options

A. Statement 1 is true and statement 2 is true and it explains statement 1.
B. Statement 1 is true and statement 2 is true and it does not explain statement 1.
C. Statement 1 is true and statement 2 is false.
D. Statement 1 is false and statement 2 is true.

Answer

D

Explanation

The momentum changes with time sincethe direction of velocity vector change with time .
But its velocity remains constant . So kinetic energy remains constant .
