Question

I should get the amplitude plzz help me​

Answer 1

$\LARGE\underline{\underline{\sf Given:}}$

• Light spring stiffness = k

• Stretched by a distance = d

• Mass attached to the end = m

$\LARGE\underline{\underline{\sf To\:Find:}}$

• Amplitude of the oscillation = ?

$\LARGE\underline{\underline{\sf Solution:}}$

We know :-

$\large{\boxed{\sf Restoring\:force=Load-Force\:due\:to\: extension }}$

Let ,

a = Amplitude of oscillation.

•°•

$\large\implies{\sf ka=mg-kd }$

$\large\implies{\sf a=\left(\dfrac{mg}{k}\right)-d}$

$\LARGE\underline{\underline{\sf Answer:}}$

Option (d)

•°• Amplitude of the oscillation is $\underline{\sf \left(\dfrac{mg}{k}-d\right)}$
