A mass $\mathrm{m}$ on an inclined smooth surface is attached to two springs as shown in figure. The other ends of both springs are attached to rigid surface. If the force constant of both spring is $k$, then the periodic time of oscillation for the system is $\ldots \ldots \ldots$ (A) $2 \pi(\mathrm{M} / 2 \mathrm{k})^{1 / 2}$ (B) $2 \pi(2 \mathrm{M} / \mathrm{k})^{1 / 2}$ (C) $2 \pi\{(\mathrm{Mg} \operatorname{Sin} \theta) /(2 \mathrm{k})\}^{1 / 2}$ (C) $2 \pi\{(2 \mathrm{Mg}) / \mathrm{k}\}^{1 / 2}$

Key Concepts

Inclined Plane Dynamics

Dynamics on an inclined plane involve breaking down the gravitational force into components parallel and perpendicular to the surface. The component mg sin? along the inclined plane plays a significant role in determining the equilibrium and restoring forces in the context of a mass attached to springs on the incline.

Effective Spring Constant in Coupled Systems

When multiple springs interact with a mass, their collective behavior can often be described by an effective spring constant. In arrangements where springs act in parallel, the individual spring constants add together, altering the overall stiffness of the system and, in turn, affecting the period of oscillation.

Simple Harmonic Motion

Simple harmonic motion is the type of periodic oscillatory motion found in systems where the restoring force is directly proportional to the displacement from equilibrium. This concept allows us to derive properties such as the angular frequency and period of oscillation, which are fundamental in analyzing mass-spring systems.

Hooke's Law

Hooke’s Law states that the force exerted by a spring is proportional to the displacement from its equilibrium position (F = -kx), where k is the spring constant. This law forms the basis for understanding how springs behave in oscillatory systems and is crucial for determining the restoring force acting on the mass.
