PhysicsEasysingle choice

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

Options:

Answer:

Solution:

For equilibrium of the block

$N = m g + Q \cos θ$

$Q \sin θ + P = μ N$

$Q \sin θ + P = μ (m g + Q \cos θ)$

$μ = (\frac{Q \sin θ + P}{m g + Q \cos θ})$
