Physics Simple Harmonic Motion (Oscillations) Spring Pendulum Single Correct MCQ
Published on: September 12, 2026

Two masses $m_1$ and $m_2$ are suspended together by a massless spring of constant k. When the masses are in equilibrium, $m_1$ is removed without disturbing the system. Then the angular frequency of oscillation of $m_2$ is

A
$\sqrt{\frac{k}{m_1}}$
B
$\sqrt{\frac{k}{m_2}}$
C
$\sqrt{\frac{k}{m_1 + m_2}}$
D
$\sqrt{\frac{k}{m_1 m_2}}$

The correct answer is:
B

With mass $m_{2}$ alone, the angular frequency

$\omega = \sqrt{\frac{k}{m_2}}$
