Question

A piece of wire is bent m the shape of
parabola y = kx2 (y-axis vertical) with a
bead of mass m on it. The bead can slide
the wire without friction. It stays at the
lowest point of the parabola when the
wire is at rest. The wire is now
accelerated parallel to the x-axis with a
constant acceleration a. The distance of
the new equilibrium position of the
bead, where the bead can stay at rest
with respect to the wire, from the y-axis
is
