Questions
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 to the vertical upwards. The block will remain in equilibrium, if minimum coefficient of friction between it and the surface is
detailed solution
Correct option is A
N = mg - QcosθP+Qsinθ=μN=μ(mg-Qcosθ)∴ μ=(P+Qsinθ)(mg-Qcosθ)Talk to our academic expert!
