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. • Q3 - The height ‘h’ at which the weight of a body will be the same as that at the same depth ‘h’ from the surface of the earth is , Radius of the earth is R and effect of the rotation of the earth is neglected • Q5 - A box weighs 196 N on a spring balance at the north pole. Its weight recorded on the same balance if it is shifted to the equator is close to , Take g = 10 ms–2 at the north pole and the radius of the earth = 6400 km • Q6 - The acceleration due to gravity on the earth’s surface at poles is g and angular velocity of the earth about the axis passing through the pole is An object is weighed at the equator and at a height h above the poles by using a spring balance. If the weights are found to be same, then h is • , h much less than R, where R is the radius of the earth • Q10 - A body A of mass m is moving in a circular orbit of radius R about a planet. Another body B of mass m/2 collides with A with a velocity which is half (v /2) the instantaneous velocity v of A. The collision is completely inelastic. Then, the combined body • Q11 - A satellite of mass m is launched vertically upwards with an initial speed u from the surface of the earth. After it reaches height R (R = radius of the earth), it ejects a rocket of mass m/10 so that subsequently the satellite moves in a circular orbit. The kinetic energy of the rocket is (G is the gravitational constant; M is the mass of the earth) • Q12 - A satellite is moving in a low nearly circular orbit around the earth. Its radius is roughly equal to that of the earth’s radius Re. By firing rockets attached to it, its speed is instantaneously increased in the direction of its motion so that it become 3/2 times larger. Due to this the farthest distance from the centre of the earth that the satellite reaches is R, value of R is • Q15 - Two planets have masses M and 16 M and their radii are a and 2a, respectively. The separation between the centers of the planets is 10a. A body of mass m is fired from the surface of the larger planet towards the smaller planet along the line joining their centers. For the body to be able to reach at the surface of smaller planet, the minimum firing speed needed is • #JEEMain2020Solutions #Gravitation #Eduniti • #JEEMain2021 #IIT #MohitGoenka • #TargetJEEAdvanced2021 #JEEmain2022 #PYQs #OneshotPYQ #JEE • #TargetNEET2021 #JEEMain2022 #IITJEE #KeplersLaw #BestJEEMainPYQ #Previousyearsquestions #GravitationBestPYQ • Join us on 🚀 Telegram Channel - https://telegram.me/edunitimg • About Faculty- • Completed Bachelors and Masters from IIT Kharagpur.
