Three blocks are arranged on a horizontal table ABCD as shown in the figure. The strings and pulleys are massless and both the pulleys stand vertical. The strings connecting blocks m 1 and m 2 are also vertical and are perpendicular to faces AB and BC which are mutually perpendicular to each other. If m 1 and m 2 are 3 kg and 4 kg respectively. Coefficient of friction between the block m 3 = 10 kg and the surface is 
= 0.6 then, frictional force on m 3 is
