Q. A massless spring having zero relaxed length has one end attached to a given point on a fixed smooth horizontal hoop of radius R, while other end is attached to a bead that is constrained to lie on the hoop. Initially the bead is at point P as shown where it is given negligible a small side kick. Find the length of spring when reaction force on bead is zero :-



(1) R√83
(2) 2R3
(3) R3
(4) R√2

Answer 1

The spring is horizontal
