Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion MCQ Question
Type: MCQ-numerical-Hard-Class 11
A particle is in uniform circular motion with a constant speed v along a circle of radius R. If the frequency of its circular motion is ν, what is the expression for its centripetal acceleration a_c in terms of ν and R?
A
a_c = 4π²ν²R
B
a_c = 2πν²R
C
a_c = 4πνR²
D
a_c = 2π²νR
Correct Answer
Option A
Detailed Explanation
Using the relation a_c = ω²R and ω = 2πν, the centripetal acceleration a_c can be expressed as a_c = (2πν)²R = 4π²ν²R.
