Answer:
Given:
Acceleration of a particle undergoing SHM is π²/2 when displacement is 2cm.
To find:
Time period of the SHM.
Formulas used:
1. Acceleration = - ω²x
2. Time period = (2π/ω).
Calculation:
As per the question:
Acceleration = - π²/2
=> - ω²x = - π²/2
=> ω²2 = π²/2
=> ω² = π²/4
=> ω = π/2 .......(1)
Now, time period is as follows:
T = 2π/ω
=> T = 2π/(π/2)
=> T = 4 seconds
So final answer is 4 seconds.
