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