The spring block system as shown in figure is in equilibrium. The string connecting blocks

A and B

is cut. The mass of all the three blocks is

m

and spring constant of both the spring is

k

. The amplitude of resulting oscillation of block

A is

A m g k B 2 m g k C 3 m g k D 4 m g k Open in App Solution

The correct option is **B**

2 m g k

Just after cutting the string, extension in spring =

3 m g k

The extension in the spring when block is in mean position

= m g k

∴ Amplitude of oscillation

A = 3 m g k − m g k = 2 m g k Suggest Corrections 1 SIMILAR QUESTIONS

Correct option is C)

We know that, n=2π 1 m k In series, k= k 1 +k 2 k 1 k 2 = 2 k 2 In parallel, k=k 1 +k 2 =2k ∴,n 1 = 2π 1 2m k and n 2 = 2π 1 m 2k hence, n 1 :n 2 =1:2 Video Explanation

questions on topic simple harmonic motion a mass of 1.5 kg this is a mass is connected to two identical springs each of force constant 307 in the figure ekadam mass is displaced from its equilibrium position by 10 cm then the period of oscillation is so what happens is that if you have a look at the given configuration this distance is fixed to let us assume they moved by a distance x so what you can see that the extension in this that is Delta X will be equal to the compression in this this this spring so basically what you see that in both of them the amount of extension same to If the amount of extension is same can be replaced is

configuration by this we can replace configuration by this basically what I want to say is that both of the strings are looking like the connected in series but they work in such a way that they are working in parallel so this is this is ke and this is 1.5 kg to the net ke net that is net spring constant of this configuration is equals to ke and King parallel that becomes he plays ke Kuchh To 2K and case 304 become too ke that is 600 Newton per metre so now we found out the unit if you have a look at simple spring block system to have a look it's pretty simple spring block system what is the value of Omega for this kind of

configuration we write Omega in here as under root came I am this is for a simple harmonic oscillator also have a simple harmonic oscillator is the value of k is different so for the given configuration Omega will be Quest to under root ke net Bade M what is the value of k 9600 so what will do will put in the values 600 / mass that is 3 by 2 that is 1.5 kg comes out to be equal to 24 2013 become 20 second inverse now I have to find out the time period of oscillation what is time period of oscillation equals to 2 pi by Omega so equals to 2 into 5 / 2020 b n that is approximately equal to

0.3 14 second so we have found out the time period of oscillation for the given configuration of the strings attached and the option matches that option B is the right answer that is the time period of oscillation for the given question will be equals to 0.314 thank you
