As shown in the figure a block of mass $\displaystyle 10$ kg lying on a horizontal surface is pulled by a force F acting at an angle $\displaystyle 30$°, with horizontal. For $\displaystyle \mu_{\mathrm{s}}=0.25$, the block will just start to move for the value of F : [Given $\displaystyle \mathrm{g}=10 \mathrm{~ms}^{-2}$ ]
