STANDARD Physics Simple Harmonic Motion MCQ Question
Type: MCQ-numerical-Medium-Class 11
When the displacement of a particle executing SHM is one-fourth of its amplitude, what fraction of the total energy is the kinetic energy?
A
16/15
B
15/16
C
3/4
D
4/3
Correct Answer
Option B
Detailed Explanation
In SHM, kinetic energy K = 1/2 mω²(A² - x²). At x = A/4, K = 1/2 mω²[A² - (A/4)²] = 15/16 of the total energy E = 1/2 mω²A².
