Questions
A horizontal force F acts on the block of mass m and the block remains stationary, the minimum force F required to pull it( = ) is:
detailed solution
Correct option is
For minimum force the object should be pulled at angle equal to angle of friction and applied force should be equal to⇒ tan θ = μ = 12hence cos θ = 25 and sin θ = 15Hence applied force F = mg5Talk to our academic expert!
