Two blocks kept on a surface of inclination `30^(@)` are connected by a weightless string. Each block is of mass 1 kg. Coefficients of friction of the lower and the upper block with the plane are `(1)/(4)` and `(1)/(2)` respectively. If the two blocks are released simultaneously, what will be the common acceleration along the inclined plane? What will be the tension in the string?
