Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion MCQ Question
Type: MCQ-numerical-Hard-Class 11
A particle is moving in a uniform circular motion with a radius of 2 meters and an angular speed of 3 rad/s. What is the magnitude of the centripetal acceleration of the particle?
A
18 m/s²
B
9 m/s²
C
12 m/s²
D
6 m/s²
Correct Answer
Option A
Detailed Explanation
For uniform circular motion, the centripetal acceleration a_c = ω²R. Here, ω = 3 rad/s and R = 2 m, so a_c = 3² * 2 = 18 m/s².
