A particle performing SHM with a frequency 10 hearts and amplitude 5 centimetre initially in left extreme position vision of displacement will be?
Verified Answer
A particle performing SHM with a frequency 10 hearts and amplitude 5 c...
X = 0.05 sin ( 20 π t + π )
In general, x = A sin ( ωt + ϕ )
Amplitude A = 5 c m
frequency f = 10
⇒ ω = 2π f
ω = 20π
⇒ x = 5 cm sin (20 πt + ϕ)
Since x = − 5 cm at t = 0
− 5 = 5 sin ϕ
⇒ ϕ = π
∴ x = 5 cm sin (20 πt + π)
As x is in meters
∴ x = 0.05 sin (20 πt + π)

Explanation of SHM with given parameters


Defining SHM


Simple Harmonic Motion (SHM) is the motion of an object back and forth around its mean position under the influence of a restoring force that is directly proportional to the displacement from the mean position.

Frequency and Amplitude



  • The frequency of SHM is the number of oscillations per second and is denoted by 'f'.

  • Here, the frequency is given as 10 Hz.

  • The amplitude of SHM is the maximum displacement of the particle from its mean position and is denoted by 'A'.

  • Here, the amplitude is given as 5 cm.



Displacement of the particle


The displacement of the particle at any time 't' can be given by the equation:

x = A cos(2πft)

where,
x = displacement of the particle
A = amplitude of SHM
f = frequency of SHM
t = time

In this case, the particle is initially in left extreme position, which means its displacement is maximum and negative. Therefore, we can write:

x = -5 cos(2π10t)

Visualization of displacement


As the particle is performing SHM, its displacement will keep changing with time. The displacement-time graph of the particle will be a sinusoidal wave with a frequency of 10 Hz and an amplitude of 5 cm. The particle will move back and forth around its mean position, crossing the mean position twice in each cycle.

Conclusion


In conclusion, the displacement of the particle performing SHM with a frequency of 10 Hz and an amplitude of 5 cm initially in left extreme position can be given by the equation x = -5 cos(2π10t). The particle will move back and forth around its mean position, crossing the mean position twice in each cycle.
