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 speed of the object remains constant.
Reason (R): The magnitude of acceleration in uniform circular motion is zero.
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.
Correct Answer
Option C
Detailed Explanation
While the speed is constant in uniform circular motion, the magnitude of acceleration is not zero; it is given by a_c = v^2/R and directed towards the center.
