Question

(3)Value of acceleration at mid-position of a particle doing simple harmonicmotion motion -

Answer 1

Answer:

it's zero at centre. The speed of particle doesn't affect the speed of it's centre.

Answer 2

Answer:

Acceleration is zero at the mid position.

Explanation:

The most basic equation of a particle in Simple Harmonic Oscillation is

F = -kx

or ma = -kx ---------------(1)

At the mid position,

Displacement, x = 0

⇒ ma = -k*0

⇒ ma = 0

⇒ a = 0
