As shown in the figure, a block of mass √3 kg is kept on a horizontal rough surface of coefficient of friction 13√3. The critical force to be applied on the vertical surface as shown at an angle 60∘ with the horizontal such that it does not move will be 3x. The value of x will be _______. (up to two decimal places)[g=10 m/s2; sin60∘=√32; cos60∘=12]
