A bead of mass m is located on a parabolic wire with its axis vertical and vertex directed towards downwards as in figure and whose equation is `x^2=ay`. If the coefficient of friction is `mu`, the highest distance above the x-axis at which the particle will be in equilibrium is

A bead of mass m is located on a parabolic wire with its axis vertical and vertex at the origin as shown in figure and whose equastion is x^(2) =4ay . The wire frame is fixed and the bead is released from the point y=4a on the wire frame from rest. The tangential acceleration of the bead when it reaches the position given by y=a is
