I solved this question few days back.. It took me 2 days to solve 🙂 Loved your explanation 😄

[@naveenyadav7226]

Fantastic one

[@bunnyjnanasai6491]

Absolutely

[@divakantdinesh]

Another beauty problem.Thank you sir

was stuck in this question sir, thank you

Nice!!

Nice sir

Sir, in problems where we have such ropes in a somewhat curved shape is cutting the rope at midpoint a general way which should be followed in such problems. In the question involving a catenary also you have used this method and arrived at a simple solution. Sira small request can you please help with pathfinder optics build -28(pg11.12) whenever you get time sir please

[@samriddhimishra557]

Sir had the question not mentioned the tension at midpoint how would we have calculated it? Is it possible to find it?

[@PhysicswithAkashGoyal]

Then mass/ mass density should be known and we can apply NLM on small section at mid point and can find tension

[@gaganjeet2147]

Sir while I tried to solve this by myself, I assumed the tension in that rope to be constant as it was massless... Obviously I was wrong but if possible sir can you please tell me how the tensions changed ?.. Thank u sir..🙏🙏!!

[@PhysicswithAkashGoyal]

You can see by taking small elements and keep in mind that there is centrepetal acceleration for each element.

[@anuragsaha8248]

Sir pls solve question 20 & 23 (build up your understanding) from Oscillation and waves.

[@jarkola9334]

Why can't we apply translational equilibrium here, why only rotational equilibrium

[@PhysicswithAkashGoyal]

There is rotation, so it can't be in translational equilibrium

[@mamtamittal3051]

Sir i have a doubt that why didnt you resolve T =T"Cosq/2 beacuse

[@PhysicswithAkashGoyal]

net force is not zero as that part of the rope is accelerated since it performing circular motion.

[@mamtamittal3051]

@@PhysicswithAkashGoyal so sir can I write the equation of circular motion on it considering the tension and equation it to centripetal acceleration , we can find the length as d and l/2 form a right angle triangle hence getting the mass too

[@PhysicswithAkashGoyal]

@@mamtamittal3051 you need to apply F ext= Mass times acceleration of center of mass and for that you need position of center of mass

[@ASHUTOSHSINGH-bd7nf]

Sir pura pathfinder ka solu upload kar dijiye

[@PhysicswithAkashGoyal]

Dear Physics Learner... There is a famous saying "rome was not built in a day". I will upload the ones which I am able to solve and find good for upload.
