NEETPhysicsRotational Motion
Assertion : A body is moving along a circle with a constant speed. Its angular momentum about the centre of the circle remains constant. Reason : In this situation, a constant non-zero torque acts on the body.
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (R) is NOT the correct explanation of (( A ) ).
- C(A) is true but (R) is false.
- DBoth (A) and (R) are false.
Correct answer
C. (A) is true but (R) is false.
