Question

If the instantaneous displacement of a particle executing SHM, whose time period is $\pi$ secs is 2 cm , the instantaneous acceleration of the particle will be

• A. $4m/s^2$
• B. $8m/s^2$
• C. $-8m/s^2$
• D. $-4m/s^2$

Answer 1

The correct option is C $-8m/s^2$

Acceleration is $a=-{\omega }^{2}x=-8$
The correct option is (c)
