This question is very very good. Beautifully crafted solution.💙

[@Aman-cp9hg]

Your explanation is very smooth.Wonderful problem

[@srslyumang]

Veryy nicee solved in first attempt ☺️ Thanks a lot for the video.

[@vedbrahmbhattiit-j4497]

Orz gawd🔥

[@poorniahmohanajayanthrao3945]

beautiful solution,sir can u please upload the solution to the "build up your understanding"'s 3rd problem. the normal per unit length one..........

[@gauravgupta2562]

sir could u please tell any channel for chemistry .. for jee advance

[@nyancat1967]

Thank You Sir I was looking for this question only of Pathfinder

[@kz_cbble9670]

Kya baat hain. Beautiful sirji👍👍

[@adityakushwahaiiitbh_2005]

Great Explanation Sir

[@sapanasaini4821]

Sir Kya aap please nlm playlist ki sari problem ki PDF de sakte ho Kya jise mers thoda time save ho jayga me 2021 advance ke liye prepare

[@kashishranjan7329]

Sir waiting eagerly for ur new videos .Sir pls continue these it's great effort from ur side sir. when there is no one to help us ur videos are the best source 🙏🙏

[@mayankd8362]

Can't we do by taking com tangential component to find net tangential force?

[@jshark3157]

Awesome 👌 Sir 😀😀💯 Great Collection

[@anveshsawarn9413]

Sir doubt when finding tangential acceleration why is dT tension ignored? ? Isn't tension for a small element an external force in tangential direction??

[@physics-concept.]

Thank you sir

Best channel

[@MANOJYADAV-gn6kg]

Sir can we do the same question by centre of mass concept and ignore the integration for calculaton of acceleration of rope .......

[@laveshbhandari9719]

I think that will give force direction tangential to CM but here we found net force along the direction of the string.

[@YeYethePooh]

Sir, Can I ask a question? When you were calculating for the acceleration. Why didn't you consider T in the equation, like you did for finding dT.

@Aniruddh Kabra orz

[@somyaagarwal865]

@Aniruddh Kabra how is normal normal to hemisphere surface, isn't it tangential ?

[@Algoner]

Super aasome problem

[@beluga8956]

🔥🔥🔥🔥🔥🔥

[@jaisonm.v9075]

Well done sir

[@shubhammittal2367]

at upper point and lower point tension is zero??????????

[@MrBenten867]

While integrating sir u have completely ignored the direction of the force , the force is always tangential to the particular element u are taking but when I integrate about the curve the direction of the force matters

[@PhysicswithAkashGoyal]

I haven't integrated the equation obtained in the last. For acceleration I integrated along the length of the string that is the tangential direction. And in this case tensions will cancel as I showed this using the pulley block system example

[@MrBenten867]

@@PhysicswithAkashGoyal sir but I don't understand when u say tangential acceleration of the rope what do I mean there are lots of tangents to the rope the obtained expression for tangential acceleration u integrated it along the rope but the direction of the tangent continuously changes I didn't Account for it kindly explain it to me sir

[@PhysicswithAkashGoyal]

@@MrBenten867 you draw FBD of small small lengths showing forces tension at the two ends and gravity. Divide rope in at least 4-5 such elements. Write NLM for all the parts. Add all equations .You should get you doubt cleared

[@kz_cbble9670]

That is calculus

[@maxwelllearning4923]

Nice
