*Multiple options can be correct

QUESTION: 1

The force which does not describe a simple harmonic motion is

Solution:

**The force which describe a simple harmonic motion is a second order linear differential equation **

**Second-order linear differential equations have a variety of applications in science and engineering.**

*Multiple options can be correct

QUESTION: 2

Choose the correct statements for the case of a one dimensional simple harmonic motion.

Solution:

The correct answers are: Force is a negative gradient of the potential, The points at which the gradient of potential are the points of stable equilibrium, The points with a negative gradient of the potential are the points of unstable equilibrium

*Multiple options can be correct

QUESTION: 3

When the phase difference between two mutually perpendicular SHMs is a quarter integer multiple of π then the path traced by a particle on which they act can be

Solution:

The correct answers are: an oblique ellipse a with the major axis making an obtuse angle with x-axis, a straight line

*Multiple options can be correct

QUESTION: 4

Select the correct options

Solution:

The period for a simple pendulum does not depend on the **mass** or the initial anglular displacement, but depends only on the **length L** of the string and the value of the gravitational field strength g.

So the correct answers are: The time period of two simple pendulum with different masses can be same, The time period of the simple pendulum depends only on length

*Multiple options can be correct

QUESTION: 5

The physical condition for simple harmonic motion is/are

Solution:

The correct answers are: restoring force must be proportional to displacement with negative sign, existence of point of stable equilibrium, presence of inertia

*Multiple options can be correct

QUESTION: 6

For a particular case of simple harmonic motion the total energy

Solution:

The correct answer is: Is a constant because the kinetic energy & potential energy at any point add upto a constant value.

QUESTION: 7

Select the correct options for a particle undergoing simple harmonic motion

Solution:

Let x=Asinωt

Then, v=dx/dt=Aωcos(ωt)

K.E.= 1/2mv^{2}

Average kinetic energy is 1/T∫(T to 0)1/2mv^{2}dt=1/4mA^{2}ω^{2}

Average potential energy is

1/T∫(T to 0) 1/2kx^{2}dt= 1/4mA^{2}ω^{2}

*Multiple options can be correct

QUESTION: 8

Choose the correct option for Lissajous figures :

Solution:

The correct answers are: Lissajous figure is the path traced by a particle when acted upon by two mutually perpendicular SHMs simultaneously, The figure depends is an ellipse in general when the two frequencies are same

*Multiple options can be correct

QUESTION: 9

Velocity of a particle undergoing simple harmonic motion is

Solution:

The correct answers are: varies with time, maximum at x = 0 and minimum at the extreme positions of the oscillations.

*Multiple options can be correct

QUESTION: 10

When a particle is being acted upon by two mutually perpendicular SHMs with same frequency & same amplitude then it traces a path which is
