An RCC square footing of side length of 3 m and uniform effective depth of 250 mm is provided for a 300 mm × 400 mm column. The line of action of the vertical compressive load passes through the centroid of the footing as well as the column. Assume that critical section for two-way shear is at the distance of one third of effective depth instead of one half of effective depth from column face. If the magnitude of the applied factored load on column is 500 kN, the nominal two-way shear stress (in N/mm2, corrected up to two decimal places) in the footing is ________
