Embibe Experts Solutions for Exercise 2: Assignment

A particle of mass $2 \mathrm{kg}$ is moving along $x$-axis under the action of force $F=-\left(\frac{{\pi }^2}{4}\right)x$ (where $F$ is in newton) and $x$ is in metre). The time period of oscillation is

If $2 \mathrm{kg}$ block connected with two massless springs as shown in figure is executing $\mathrm{SHM},$ then time period of block is (Surface is smooth)

Which of the following does not represent $\mathrm{SHM}?$

A particle executing $\mathrm{SHM}$ along $x$ axis which is described by $x=5\sin \left(\frac{\pi t}{2}\right).$ Phase of particle at $t=1 \mathrm{s}$ is

A particle moves such that acceleration is given by $a=-9 x.$ The period of oscillation is (symbols have their usual meanings)
