Vernier caliper  How to find least count? Watch video 💡 What is Least Count? Least Count (L.C.) is the smallest measurement that an instrument can read accurately. It tells you the precision of the instrument — basically, how fine a measurement it can take. 🧠 Think of it as: "How small can this device measure?" 🔍 How to Find Least Count of Any Apparatus? There’s a universal formula : Least Count = Value of One Main Scale Division / Number of Divisions on the Vernier or Dial Scale But depending on the instrument, the method varies. Here's how you do it for common tools: 1. Ruler / Scale (Meter Scale) Each division = 1 mm = 0.1 cm ➡️ L.C. = 0.1 cm 2. Vernier Caliper ✅ Formula: L.C. = 1 MSD - 1 VSD (Or simply: L.C. = Smallest reading on main scale / number of vernier divisions ) 📌 Example: 1 cm = 10 divisions → 1 MSD = 1 mm Vernier has 10 divisions = 9 mm ➡️ L.C. = 1 mm – 0.9 mm = 0.1 mm 3. Screw Gauge / Micrometer ✅ Form...

  Dimensional analysis is a powerful tool in physics that helps you: Check the correctness of equations Convert units Derive relationships between physical quantities Download class 11 physics notes ⚙️ What is Dimensional Analysis? It’s the method of expressing physical quantities in terms of basic dimensions : M → Mass L → Length T → Time (Others like A for current, K for temperature if needed) 🧠 Think of it like finding the DNA of any physical quantity. 🧮 Common Examples Quantity Dimensional Formula Velocity [ L T − 1 ] [LT^{-1}] [ L T − 1 ] Acceleration [ L T − 2 ] [LT^{-2}] [ L T − 2 ] Force (F = ma) [ M L T − 2 ] [MLT^{-2}] [ M L T − 2 ] Energy (E = F×d) [ M L 2 T − 2 ] [ML^2T^{-2}] [ M L 2 T − 2 ] Pressure (P = F/A) [ M L − 1 T − 2 ] [ML^{-1}T^{-2}] [ M L − 1 T − 2 ] ✅ Uses of Dimensional Analysis Checking Equation Validity Example: Is s = u t + 1 2 a t 2 s = ut + \frac{1}{2}at^2 s = u t + 2 1 ​ a t 2 dimensionally correct?

  Questions on Differentiation (With Answers) Here are a few solved questions based on differentiation concept. 1. Differentiate x 5  with respect to x. Solution: Given, y = x 5 On differentiating w.r.t we get; dy/dx = d(x 5 )/dx y’ = 5x 5-1  = 5x 4 Therefore, d(x 5 )/dx = 5x 4 2. Differentiate 10x 2  with respect to x. Solution: y = 10x 2 y’ = d(10x 2 )/dx y’ = 2.10.x = 20x Therefore, d(10x 2 )/dx = 20 x 3. Differentiate 20x -4  + 9. Solution: y = 20x -4  + 9 y’ = d(20x -4  + 9)/dx y’ = d(20x -4 )/dx + d(9)/dx y’ = -4.20.x -4-1 +0 y’ = -80x -5 Therefore, d(20x -4  + 9)/dx = -80x -5 4. Differentiate sin(3x+5) Solution: Say, y = sin (3x+5) dy/dx = d[sin(3x+5)]/dx = cos (3x+5) d(3x+5)/dx [ By chain rule] = cos (3x+5) [3] y’ = 3 cos (3x+5) d[sin(3x+5)]/dx = 3 cos (3x+5) 5. Differentiate tan 2 x. Solution: Say, y = tan 2 x dy/dx = d(tan 2 x)/dx = 2tan 2-1 x. d(tan x)/dx = 2tan x sec 2 x d[tan 2 x]/dx = 2tan x sec 2 x 6. Compute the derivative of f(x) ...
