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 `mu = 0.6 ` then, frictional force on `m_3` is
