Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 11
Assertion (A): In uniform circular motion, the speed of the object is constant. | Reason (R): The centripetal acceleration is directed towards the center, hence it cannot change the speed of the object.
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 A
Detailed Explanation
In uniform circular motion, the speed is constant because centripetal acceleration only changes the direction of velocity, not its magnitude, as per the NCERT context.
