NEET Physics Uniform Circular Motion MCQ Question
Type: MCQ-fact-Medium-Class 11
What is the magnitude of the centripetal acceleration for an object moving with a constant speed v in a circular path of radius R?
A
v^2 / R
B
v / R^2
C
R^2 / v
D
v^2 * R
Correct Answer
Option A
Detailed Explanation
The magnitude of the centripetal acceleration is given by the formula a_c = v^2 / R, which indicates that it depends on the square of the speed and inversely on the radius of the circular path.
