A block of mass √3 kg is on a rough horizontal surface with μ = 1/(3√3). A force is applied to its vertical face at 60° as shown. The critical force is written as 3x. Find x, using the answer convention of the source.

At the limiting condition, resolve the applied force into horizontal and vertical components and set the required friction equal to μN. The printed source answer key gives x = 3 for this numerical question; this value has been preserved in the upload sheet.
