The displacement of a particle executing SHM is given by $y = 4 cos^{2} (t /2) sin (1000 t)$ . This expression may be considered as the result of the superposition of how many simple harmonic motions?

Options:

Answer:

Solution:

$4 cos^{2} (t /2) = 2 (1 + cos t)$ , so $y = 2 sin 1000 t + sin 1001 t + sin 999 t$ : three SHMs.
