A block of mass is placed over a frictionless horizontal surface. Another block of mass is placed over it which is connected with a light string passing over two pulleys fastened to the block. A force, , is applied horizontally to the free end of the string. Friction coefficient between two blocks is 0.6. The portion of the string between block and the upper pulley is horizontal as shown in figure. Pulley, string and connecting rods are massless (Take ). Using the above information, answer the following questions The magnitude of acceleration of the block is
