NEET Physics Uniform Circular Motion MCQ Question
Type: MCQ-numerical-Hard-Class 11
An object is moving with a constant speed of 10 m/s in a circular path of radius 5 m. What is the magnitude of the centripetal acceleration of the object?
A
2 m/s²
B
10 m/s²
C
20 m/s²
D
5 m/s²
Correct Answer
Option C
Detailed Explanation
The magnitude of centripetal acceleration is given by v²/R, where v is the speed and R is the radius. Substituting v = 10 m/s and R = 5 m, we get 10²/5 = 20 m/s².
