Consider the figure given below in which a particle of weight W resting a smooth (frictional less) inclined plain AB with the help of force F acting on the particle at angle θ with the line AB.

find the force F and normal reaction
  • a)
    (Wcosθ)/sinα, [Wcos(α - θ)]/cosθ
  • b)
    (Wsinα)/cosθ, [Wsin(α + θ)]/cosθ
  • c)
    (Wsinα)/cosθ, [Wcos(α + θ)]/cosθ
  • d)
    None on these
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Consider the figure given below in which a particle of weight W restin...
Using law of Sine
F/sin(180 - α) = N/sin(90 + α + θ) = W/sin(90 - θ)
Solving this

F = (Wsinα)/cosθ, N=[Wcos(α+θ)]/cosθ
