As shown in the figure, a block of mass `sqrt3` kg is kept on a horizontal rough surface of coefficient of friction `1/(3sqrt3)` The critical force to be applied on the vertical surface as shown at an angle `60^@` with horizontal such that it does not move, will be 3x. The value of x will be
`[g=10m//s^2,sin60^@=sqrt3/2,cos60^@=1/2]`
