The resultant force acting on a particle executing simple harmonic motion is 4N when it is 5cm away from the centre of oscillation. Find the spring constant.

Explanation

To find the spring constant \( k \) for a particle executing simple harmonic motion, we can use the formula for the force acting on the particle:

1. **Understand the relationship**: The force \( F \) acting on a particle in simple harmonic motion is given by Hooke's Law:
\[ F = -kx \]
where \( k \) is the spring constant and \( x \) is the displacement from the equilibrium position.
