The x-coordinate of a particle varies according to the relation $x = 8 cos^{2} 50 t$ . Which of the following is incorrect about this motion?

Answer:

Solution:

$x = 8 cos^{2} 50 t = 4 + 4 cos 100 t$

This is SHM about x = 4 with amplitude 4; x varies from 0 to 8.

So the amplitude is 4, not 8; statement D is incorrect.

Answer: D
