Скачать или смотреть [JEE MAIN 2020] Bead on a rotating Parabolic wire

SOLVED EXAMPLE FROM JEE MAINS 2020
Chapter Name : CIRCULAR MOTION
Topic name : CENTRIFUGAL FORCE

A bead of mass m stays at point P(a, b) on a wire bent in the shape of a parabola y = 4Cx^2 and rotating with angular speed ω (see figure). The value of ω is (neglect friction):
(a) 2√2gC (b) 2√gC (c) √(2gC)/(ab) (d) √2g/C
