Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): In uniform circular motion, the velocity of the object remains constant.
Reason (R): The centripetal acceleration is always directed towards the center and its magnitude is constant.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option D
Detailed Explanation
In uniform circular motion, the speed is constant but the velocity changes due to its direction changing continuously. Hence, A is false. However, R is true as centripetal acceleration always points towards the center and has a constant magnitude.
