Question

A particle is shm crosses its equilibrium position at time t =2

Answer 1

ANSWER:

SHM stands for Simple Harmonic Motion.

It is a very important phenomenon in Mechanics which is a branch of Physics.

SHM is a special type of motion.

• It shows a Periodic or Oscillatory Behavior.
• In this motion, the object moves due to a Restoring Force.
• This Force is proportional. The nature of proportionality is direct.
• The direction of this restoring force is Opposite. It is opposite to the direction of displacement from the Mean Position.
• The time taken by a body showing SHM to complete 1 cycle is its Time Period.
• It is denoted by "T".

In the question, it is given that A particle is in SHM.  It is crossing its Equilibrium position. It is crossing it at t = 2.

This statement refers to the Period of the particle actually. The body is in equilibrium at its Mean Position. And it goes from this position twice to complete 1 Cycle. So it is 4 units for this particle.
