Dear Swarnendu,
You know the load, you know the mounting method (from the explanations, I presume it to be cantilevered). any handbook would give you the bending moment at the point of fixing. Else, you can even calculate it from first principles.
Find the Moment of Inertia of the cross section, find the section modulus (Z = I/y) where Z is the section modulus, I area moment of inertia and "y" the distance of the extreme fibre from the CG.
This would give you the bending stress. Based on the Allowable stress (material property), you may now calculate the minimum dia.
