Physics - NLM Question with Solution | TestHub

The system is at rest ( ${\mathrm{F}}_{\text{net }}=0$ ) For maximum $\mathrm{M}/\mathrm{m}$; Limiting friction will be acting on both blocks (at contact surfaces). ${\mathrm{F}}_{{\mathrm{L}}_1}+{\mathrm{F}}_{{\mathrm{L}}_2}=$ Net pulling force on the whole system $\mu \mathrm{mg}+\mu \mathrm{Mg}\cos \theta =\mathrm{Mg}\sin \theta$ $\mathrm{Mg}(\sin \theta -\mu \cos \theta )=\mu \mathrm{mg}$ $\frac{\mathrm{M}}{\mathrm{m}}=\frac{\mu }{(\sin \theta -\mu \cos \theta )}$
