Oscillations Te...

Two masses $$m_1$$ and $$m_2$$ are suspended together by a massless springs 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 

What is constant in S.H.M.

A mass $$m$$ is suspedend from the two coupled springs connected in series. The force constant for springs are $$K_1$$ and $$K_2$$. The time period of the suspended mass will be 

A system exhibiting $$S.H.M$$ must possess

Which of the following is not true? In the case of a simple pendulum for small amplitudes the periodic of oscillation is

A simple pendulum is sec up in a trolley which moves to the right with an acceleration $$a$$ on a horizontal plane. Then the thread of the pendulum in the mean position makes an angle $$\theta$$ with the vertical

A particle moving along the $$x-$$axis execute simple harmonic motion, then the force acting on it is given by

The period of simple pendulum is measured as $$T$$ in a stationary lift. If the lift moves upward with an acceleration of  $$5\ g$$, the period will be

Mark the wrong statement

The time period of a simple pendulum is $$2$$ sec. If its length is increased $$4$$ times, then its period becomes
