Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Which of the following statements about uniform circular motion is correct?
A
The centripetal acceleration is directed away from the center of the circular path.
B
The magnitude of centripetal acceleration remains constant while its direction changes.
C
The velocity of the object is directed towards the center of the circle.
D
The object in uniform circular motion has a changing speed throughout its motion.
Correct Answer
Option B
Detailed Explanation
In uniform circular motion, the magnitude of centripetal acceleration is constant (given by a_c = v^2/R), but its direction changes as it always points towards the center of the circle, as stated in the NCERT context.
