Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 11
Assertion (A): In uniform circular motion, the velocity vector of the object is constantly changing. | Reason (R): The velocity of an object in uniform circular motion is constant because the speed is uniform.
A
Both A and R are true, and R explains A.
B
Both A and R are true, but R does not explain A.
C
A is true, but R is false.
D
A is false.
Correct Answer
Option C
Detailed Explanation
In uniform circular motion, the speed is constant, but the direction of the velocity vector changes continuously, thus the velocity is not constant. The reason provided is incorrect.
