A particle executes simple harmonic motion along a straight line with an amplitude $A$. The potential energy is maximum when the displacement is
A$ \pm A$
B
Zero
C$ \pm \frac{A}{2}$
D$ \pm \frac{A}{{\sqrt 2 }}$

A$ \pm A$
a (a) $P.E. = \frac{1}{2}m{\omega ^2}{x^2}$
It is clear $P.E.$ will be maximum when $x$ will be maximum i.e., at $x = \pm A$

Two pendulums differ in lengths by $22\,cm$ . They oscillate at the same place such that one of them makes $15\,oscillations$ and the other makes $18\,oscillations$ during the same time. The lengths (in $cm$ ) of the pendulums are
A particle of mass $200 \,gm$ executes $S.H.M.$ The restoring force is provided by a spring of force constant $80 \,N / m$. The time period of oscillations is .... $\sec$
Two masses $m_1=1 \,kg$ and $m_2=0.5 \,kg$ are suspended together by a massless spring of spring constant $12.5 \,Nm ^{-1}$. When masses are in equilibrium $m_1$ is removed without disturbing the system. New amplitude of oscillation will be .......... $cm$
A particle performs $SHM$ on $x-$ axis with time period of $0.5\,sec,$ such that it's velocity is zero at $x = -3\,cm$ and at $x = 9\,cm$. It was located at $x = 0$ and moving in negative $'x'$ at $t = 0$. The equation of $SHM$ of the particle is
