Sir if there's no any external force acting on the system then how the two bodies are displaced towards spring???

[@AnshuGSharma]

The spring is in the system, and acts on the blocks.

[@vroomie]

zero NET external force. NET means sum of all.

[@SumaidSyed]

Sir,how the springs K1 and K2 are in series?And how did you calculate K1 and K2 from lengths I did not understand?

[@physicsgalaxyworld]

This I have already explained in fundamental classes of forces about spring combinations as well as calculations of k1 and k2....

[@SumaidSyed]

I watched all fundamental videos,I did not find spring combination section..

[@physicsgalaxyworld]

watch fundamental class-6 of Newton's Laws again... its covered in that...

[@Hj-nn8td]

sir could you please explain that why time period is same for both? and it would be great if u could provide a link to video for the proof of k1=kl/l1

[@physicsgalaxyworld]

Time period is same because no external force is acting on the system so system com will remain at rest so both bodies will move in sync... analysis of cutting of spring is there in fundamental class - 6 of NLM... link I am giving here... kzbin.info/www/bejne/e2PMqH-im9KshNE
