Physics-Simple Harmonic Motion
NEET Physics Simple Harmonic Motion MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Consider a diagram of a mass-spring system where a mass is attached to two identical springs on either side. The mass is displaced from its mean position and released. Which of the following expressions correctly represents the net force acting on the mass at any displacement x from the mean position?

A
F = -2kx
B
F = -kx
C
F = kx
D
F = 2kx
Correct Answer
Option A
Detailed Explanation
The net force acting on the mass is given by F = -2kx, as the force is proportional to the displacement and is directed towards the mean position, characteristic of simple harmonic motion.
