Physics - Circular Motion question

A right circular cone of semiangle 60° is fixed with its axis vertical and its vertex downwards. A small particle performs circles steadily on the inside of the cone at a constant speed of 70 cm/s. The distance of the particle from the vertex will be

Sorry, if I am late, but, just make the FBD of the particle and balance the forces. The centripetal force will give you the radius of the particle which will give the height of the particle from the vertex using trigonometry and 60 degrees angle.
