As shown in the figure, a block of mass $\sqrt { 3 } \mathrm {~kg}$ is kept on a horizontal rough surface of coefficient of friction $\frac { 1 } { 3 \sqrt { 3 } }$. The critical force to be applied on the vertical surface as shown at an angle $60 ^ { \circ }$ with horizontal such that it does not move, will be $3x$. The value of $x$ will $\left[ g = 10 \mathrm {~m} \mathrm {~s} ^ { - 2 } ; \sin 60 ^ { \circ } = \frac { \sqrt { 3 } } { 2 } ; \cos 60 ^ { \circ } = \frac { 1 } { 2 } \right]$ $\mu = \frac { 1 } { 3 \sqrt { 3 } }$
