For a heavily damped harmonic oscillator, what describes its return to the equilibrium position?
A. It oscillates rapidly with decreasing amplitude.
B. It oscillates exactly once before stopping.
C. It never returns to the equilibrium position.
D. It returns to equilibrium slowly without any oscillation.
Answer: Option D
Solution (By JKSSB Mock Tests)
Damping opposes the motion of an oscillator (like a pendulum in thick oil). In 'underdamped' systems, it oscillates with decaying amplitude. In 'critically damped' systems, it returns to equilibrium as fast as possible without oscillating. In 'overdamped' or heavily damped systems, the resistive force is so strong that it slowly creeps back to equilibrium without ever crossing it to oscillate.
