Question

A block of mass m lying on a rough horizontal plane is acted upon by a horizontal force P and another force Q inclined at an angle θ to the vertical. The block will remain in equilibrium if the coefficient of friction between it and the surface is, P + Q sin ⁡ θ m g + Q cos ⁡ θ, P cos ⁡ θ + Q m g - Q sin ⁡ θ, P + Q cos ⁡ θ m g + Q sin ⁡ θ, P sin ⁡ θ - Q m g - Q cos ⁡ θ

MARKS App · Accepted Answer

For equilibrium of the block N = m g + Q cos ⁡ θ Q sin ⁡ θ + P = μ N Q sin ⁡ θ + P = μ ( m g + Q cos ⁡ θ ) μ = Q sin ⁡ θ + P m g + Q cos ⁡ θ
