12: Simple Harmonic Motion
- #10For a particle executing simple harmonic motion, the acceleration is proportional to
(a) displacement from the mean position
(b) distance from the mean position
(c) distance travelled since t = 0
(d) speeddigAnsr: aAns : (a) displacement from the mean position
For S.H.M.,
F = -kx
ma = - kx (F = ma)
or,
a = `` -\frac{k}{m}x``
Thus, acceleration is proportional to the displacement from the mean position but in opposite direction.
