Sure!! Soon!!

Thank you!!

Good morning: Thank you!!

NV sir is a legend!

Correct . Nv sir doesn't need introduction.

By saying so, you are demeaning others. Salute to NV Sir 🫡

D: 9

@IIT-JEE-Mains-Advanced-Physics could you explain pls

@@giorgikapanadze-f2j Stress=Force/Area. Force= Mass*g; and Mass in terms of volume is proportional to the linear dimension cubed (𝐿^3 ), while area is proportional to the linear dimension squared (𝐿^2 ). Thus, the ratio of volume to area results in a linear dimension (𝐿). For more details, please see this video: th-cam.com/video/ReEjmYurBbA/w-d-xo.html.

My bad!! 🙏

Using AI!!

@@IIT-JEE-Mains-Advanced-Physics which Ai tool sir, if u don't mind saying, btw great content sir 🙏 , post AITS solutions too sir

@@TheodorerooseveltTheFourTH I use customized version of POE.😇

I will try to further improve!! 😇

Thank You!!

Sure!!!

We don't!! You can assume any direction of motion. However,this principle holds for any number of blocks and any arrangement (whether on pulleys, inclined planes, etc.). The sign of the result will always indicate whether your assumed directions are correct or if the motion is in the opposite direction. You can choose any direction for the blocks' motion at the start, and the signs in the solution will guide you to the correct directions. The physics remains the same regardless of your initial assumption!😇

Thank you!!

Thanks!!

Sure I will continue with class 11!! Chemistry and maths will be a long shot!!😊

@@IIT-JEE-Mains-Advanced-Physics thankuuu sir ❤️

Thank you!!

Sure!! WIP!!

@@IIT-JEE-Mains-Advanced-Physics waiting for it ❤️

Thank You!!

Sure!! WIP!!

Sure!! WIP!!

I will try to improve!!😇

Yes, it is possible to get a decent rank with 3 months of dedicated preparation. It will require a well-structured plan, focus on key concepts, regular practice, and a lot of hard work. With consistent effort and a strategic approach, you will achieve good results.

@@IIT-JEE-Mains-Advanced-Physics I am good at chemistry but my physics and maths is almost at zero level 🙂Sir I understands the theoretical concepts of physics but idk why I am not able to do any numerical after looking at questions it feels like I wasted my whole time studying the chapter if I am not able to solve single numerical by myself

@@anjaliMishra-g9n It's completely normal to struggle with applying theoretical concepts to solve physics and math problems. Your strength in chemistry and understanding of physics theory, so more than half of the work is done!!. Struggling with numerical is part of learning, and persistence is key, so view your efforts as building a foundation. Start with basic problems, break them down into smaller parts, and gradually progress to more complex ones. The more you practice, the better you'll recognize patterns that help you solve similar problems faster. Review your mistakes to understand why you were not able to solve-that’s where real learning happens. Keep in mind that solving problems improves your logical thinking, even if progress feels slow. In physics especially, most of the problems revolve around key principles like balance/equilibrium/ conservation of forces/energy,, which can simplify complex scenarios. Stay patient, practice consistently, and celebrate small wins along the way-numerical will start to click!

@@IIT-JEE-Mains-Advanced-Physics thankyou sir

@@IIT-JEE-Mains-Advanced-Physics sir genuine reply Diya kro chat gpt ka copy paste Mt kiya kriye 🤥

Thank you too!👍

@@IIT-JEE-Mains-Advanced-Physics I see. If it's negative, then I just flip the direction 180 degrees. If it's positive, then my initial assumption was correct. Is that what you mean?

@@angelaguilar497 Yes, that's exactly what I mean! If the result is negative, you simply flip the direction by 180 degrees from your initial assumption. If the result is positive, your initial assumption about the direction was correct. So: Negative result → The motion is in the opposite direction to what you assumed. Positive result → Your assumption about the direction is correct.

All the best

Really !! what should be correct answer?

@@Kamyasingh-v2bAfter getting sin inverse function we insert the limits from 0 to y so it becomes sin ^-1 (y-1) -3pi/2

the correction should be it should he 3pi/2 instead of pi/2

@@psychoranzer2495 The range of the arcsine function, (arcsin(x)), is restricted to (- pi/2, pi/2). This means that arcsin(y - 1)) will give a value within this range. Therefore, subtracting 3pi/2 would be inconsistent with the standard result and would take the expression outside of the expected range. This adjustment comes from the fact that at y = 0 , arcsin(-1) gives -pi/2, which is why we add pi/2 to bring the result back into the appropriate range. Subtracting 3pi/2 would lead to an incorrect phase shift.
