UM-7 | Vernier Calipers_Least Count, Zero Error, Measured & True Value with NEET & JEE Queations

Part-7 | 11th Units & Measurements | Vernier Calipers_Least Count, Positive & Negative Zero Error, Measured & True Value with NEET, CBSE & JEE Questions | Akash Sir Physics Timeline of Topics👇 00:00 | Introduction 00:58 | Vernier Calipers and its least count 12:12 | Measured value and true value 14:28 | Positive and negative zero error 19:40 | JEE 2024 & NEET_Assertion(A): In Vernier Calipers, if positive zero error exists, then while taking measurements, the reading taken will be more than the actual reading. Reason(R): The zero error in Vernier Calipers might have happened due to manufacturing defect or due to rough handling. 21:08 | JEE 2024 & NEET_If 50 Vernier divisions are equal to 49 main scale divisions of a travelling microscope and one smallest reading of main scale is 0.5mm, the Vernier constant of travelling microscope is_ 23:41 | JEE 2022 & NEET_A travelling microscope is used to determine the refractive index of a glass slab. If 40 divisions are there in 1 cm on main scale and 50 Vernier scale divisions are equal to 49 main scale divisions, then least count of travelling microscope is___ x10-6m. 26:22 | NEET 2024 & JEE_In a Vernier Calipers, (N+1) divisions of Vernier scale coincide with N divisions of main scale. If 1 MSD represents 0.1mm, the Vernier constant (in cm) is: 28:16 | JEE 2022 & NEET_In a Vernier Calipers, 10 divisions of Vernier scale is equal to 9 divisions of main scale. When both jaws of Vernier calipers touch each other, the zero of the Vernier scale is shifted to the left of zero of the main scale and 4th Vernier scale division exactly coincides with the main scale reading. One main scale division is equal to 1mm. While measuring diameter of spherical body, the body is held between two jaws. It is now observed that zero of the Vernier scale lies between 30 and 31 divisions of main scale reading and 6th Vernier scale division exactly coincides with the main scale reading. The diameter of spherical body will be: 34:18 | JEE 2023 & NEET_In an experiment with Vernier calipers of least count 0.1mm, when two jaws are joined together, the zero of Vernier scale lies right to the zero of main scale and 6th division of Vernier scale coincides with the main scale division. While measuring the diameter of a spherical bob, the zero of Vernier scale lies in between 3.2cm and 3.3 cm marks and 4th division of Vernier scale coincides with the main scale division. The diameter of bob is measured as: #asdphysics #asdphysicsacademy #akashsirphysics #asdsirphysics #asd #asdacademy #physicswallah #physics #neet #jeemains #neetpreparation #physicsneet #physicsclass #neetwallah #error #leastcount #measurement #units_and_measurements #unitsandmeasurements #vernier #verniercaliper #zeroerror #positivezeroerror #negativezeroerror #vernierconstant #measuredvalue #truevalue #meanvalue #msd #msdhoni #mainscale #vernierscale #depth Follow Us: Facebook:   / asdphysics   Instagram:   / asd_physics_academy   Telegram:https://t.me/asdphysicsacademy Twitter:   / asdphysics   WhatsApp:https://bit.ly/3VSi3uF
