✅JEE Advanced PYQs - https://bit.ly/2SCybTR ✅JEE Advanced Problem Series - https://bit.ly/38hJGEj Questions Discussed: 1. A planet of radius R = 1/10 (radius of Earth) has the same mass density as Earth. Scientists dig a well of 10 depth R5 on it and lower a wire of the same length and of linear mass density 10–3 kg m–1 into it. If the wire is not touching anywhere, the force applied at the top of the wire by a person holding it in place is (take the radius of Earth = 6 × 10^6 m and the acceleration due to gravity on Earth is 10 ms–2) 2. A thin uniform annular disc (See figure) of mass M has outer radius 4R and inner radius 3R. The work required to take a unit mass from point P on its axis to infinity is ? 3. A spherical body of radius R consists of a fluid of constant density and is in equilibrium under its own gravity. If P(r) is the pressure at r, then the correct option(s) is (are) 4. A spherically symmetric gravitational system of particles has a mass density ρ={ρ0 for r less than equal to R, 0 for r more than R , where ρ0 is a constant. A test mass can undergo circular motion under the influence of the gravitational field of particles. Its speed v as a function of distance r from the center of the system is represented by #Gravitation #JEEAdvancedPYQs #Eduniti #JEEAdvanced2021 #JEEMain #IITJEE #NEET #JEEMain2021 #JEEMain2022 About Faculty- Completed Bachelors and Masters from IIT Kharagpur. Having an experience of +3 Years in teaching I reckoned the urge within me to help students appreciate the subject by delivering the toughest concept in simplest manner through practical demonstrations and visual aids.
