JEE MainPhysicsCircular MotionMCQ+4 / −1
A smooth wire of length 2 π\piπ r is bent into a circle and kept in a vertical plane. A bead can slide smoothly on the wire. When the circle is rotating with angular speed ω\omegaω about the vertical diameter AB, as shown in figure, the bead is at rest with respect to the circular ring at position P as shown. Then the value of ω\omegaω 2 is equal to - JEE Main 2019 (Online) 12th April Evening Slot Physics - Circular Motion Question 60 English
