JEE MAIN - Physics (2022 - 27th June Morning Shift - No. 15)
The displacement of simple harmonic oscillator after 3 seconds starting from its mean position is equal to half of its amplitude. The time period of harmonic motion is :
6 s
8 s
12 s
36 s
Wyjaśnienie
Time taken by the harmonic oscillator to move from mean position to half of amplitude is $${T \over {12}}$$
So, $${T \over {12}}$$ = 3
T = 36 sec.
