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