wallA block of mass m = 2 kg isheld stationary against a wallby applying a horizontalmF-force F on it as shown in Fig.5.41. If the coefficient of fric-tion between the block andthe wall is u = 0.25, find theminimum value of F requiredto hold the block against thewall. Take g = 10 ms.Fig. 5.41

Solution:-Given thatmass of block (m)=2 kgcoefficient of friction (μ)=0.25g=10 m/s2
