In this video I am
In this video I am explaining vertical circular motion in accelerated frame on which several questions are asked in IITJEE & NEET. Vertical circular motion is a fundamental topic which is analyzed using effective gravity or effective acceleration when performed in an accelerated frame.
Watch this video to understand this very fundamental topic explanation with the help of animations.
Practice Quiz Questions based on concepts explained in this video -
Students are advised to solve below questions and find, out of given questions below which question(s) are given with wrong answer(s). Correct answer with explanation will be shared in comments after two days. Q. 5 given below is only for students preparing for JEE Advanced. If any student is solving Q5, he/she is requested to share the solution in comment box so that it can be checked if you solved it correctly or not.
(1) An elevator is accelerating down at 2m/s² in which a simple pendulum is suspended on one of its vertical wall with string length 2m. The string is pulled aside and bob is held horizontally with string tight. Find minimum downward speed with which bob is to be thrown so that bob completes the vertical circle.
[6.93m/s]
(2) An elevator is accelerating up at 5m/s² in which a simple pendulum is suspended on one of its vertical wall with string length 5m. The string is pulled up so and bob is held with string vertical and tight. Find minimum horizontal speed with which bob is to be thrown so that bob completes the vertical circle.
[11.18m/s]
(3) An elevator is accelerating down at 13m/s² in which a simple pendulum is suspended on one of its vertical wall with string length 6m. From equilibrium position of bob it is thrown perpendicular to initial string length. Find minimum projection speed of bob so that bob completes the vertical circle.
[9.49m/s]
(4) Inside a box car accelerating on a horizontal road with acceleration 5m/s² a simple pendulum is suspended on one of its vertical wall with string length 4m. From equilibrium position of bob it is thrown perpendicular to initial string length. Find minimum projection speed of bob so that bob completes the vertical circle.
[22.36m/s]
(5) In previous question if bob is held vertically with string tight, find minimum tangential projection speed of bob required for bob to complete its vertical circular motion.
[7.36m/s]
(Q. 5 is mainly for students preparing for JEE Advanced. NEET Aspirants need not solve this question)
