Question

A small particle of mass m is given an initial velocity v0 tangent to the horizontal rim of a smooth cone at a radius r0 from the vertical centre line as shown in the figure. As the particle slides to point B, a vertical distance h below A and a distance r from the vertical centre line, its velocity v makes an angle theta with the horizontal tangent to the cone through the point B
