Doubts and answers on every NEET Physics chapter, by students.
Most marks lost in mechanics come from a short list of repeat traps. Here is the list, with a quick fix for each.
Sorry, 1 AM, can't sleep, solid mechanics is eating me.
The chapter is short but formula-heavy. Which derivations are worth knowing, and which results can simply be learned?
Second attempt, going back to basics and trying not to just mug formulas this time. Electrostatic Potential chapter. For an electric dipole, the potential at a point on the equatorial line is zero since V = \dfrac{p\cos\
Doing wave optics PYQ-style questions and this one keeps eating my marks. Q: Unpolarised light of intensity I 0 passes through two polaroids whose pass axes make an angle of 60°. What's the intensity of the emergent ligh
This is making me crazy, and I know it's a classic NEET concept so I can't skip it. The binding energy per nucleon curve rises steeply for light nuclei, peaks near iron A around 56 and then falls slowly for heavy nuclei.
I am studying alternating current from NCERT. I understand that household voltage is written as 220 V but the peak is about 311 V. I want to understand why. My teacher said rms value comes from the average of \sin^2 bein
Revising Motion in a Plane from the start for my drop year plan week 2, Physics block . I made a template for each topic with "formula / common error / one solved example" and the last box for this topic is empty because
Rotation looks like a new subject, but it is mostly linear motion in a different costume. Here is a way in that cuts down what you need to memorise.
Work, Energy and Power. I made a table of "who does positive / negative / zero work" and several rows don't feel right to me. W = \vec F\cdot\vec d = Fd\cos\theta . I get: - Lifting a book at constant speed by h : work d
Study-planner girl with a doubt that doesn't fit into a planner. 😅 De Broglie: \lambda = h/p . For an electron accelerated through V volts, I know \lambda = \dfrac{1.227}{\sqrt{V}} nm. For V = 54 this gives 0.167 nm, and
One wrong sign flips real to virtual and magnified to diminished. Here is a single convention, one routine, and two worked examples.
