Question

question 9
.... 10
...... 11

Answer 1

And. 9 Oscillatory
Ans. 10 Translaory
Ans.11 SHM and SHM is oscillatory Motion too.


Now.
Ans 9
F = -5 (x-2)^3

Acceleration is negative when (x-2) is positive and positive when (x-2) is negative.
Hence, it is an Oscillatory Motion about x = 2


Ans. 10

F = -5(x-2)^2

The motion depicts an non uniform translatiry motion as the acceleration just keeps increasing in the negative direction about the point x = 2 .
This is because ( x-2) is always positive.

And. 11.

F = -5(x-2)

Here, Force varies linearly with x and always attractive in nature.
This represents SImple Harmonic Motion.
SHM is also a type of Oscillatory Motion.
