A boby is moving in a room with a velocity of `20m//s` perpendicular to the two walls separated by 5 meters .There is no friction and the collisionnn with the walls are elastic.

A

Not periodic

B

Periodic but not simple harmonic

C

Periodic and simple harmonic

D

Periodic with variable time period

Text Solution

Verified by Experts

The correct Answer is:
B
Body collides elastically with walls of room. So, there will be no loss in its energy and it will remain colliding with walls of room after a regular time interval, so it.s motion will be periodic. Since acceleration is not proportional to displacement, so it.s motion in not SHM.
