plz answer 3.3 as i did the 1st two

Question 1 The figure below shows a mass, 5kg at rest on the smooth inclined surface of a right cone which has an included angle of 100°. The mass is supported by a light rod pivoted at O on the top of the cone, and is parallel to its sloping surface. Draw system of forces 3.1) Calculate the normal reaction between the mass (A) and the surface of the cone (remember it is at rest) [2] 3.2) The system is now made to tum at a constant angular velocity of 36r.p.m, Calculate: 3.2.1) The normal reaction between the mass and the cone [3] 3.2.2) The tensile force in the rod [2] 3.3) Determine the angular velocity in r.p.m. at which point of losing contact with the surface of the cone.
