Questions
If four forces act at a point ‘O’ as shown in the figure in a plane and if O is in equilibrium then the value of 'θ' & ‘P’ are
a
150 , 10√2 N
b
450, 10 N
c
750 , 10√2 N
d
900 , 20N
detailed solution
Correct option is D
As 'O' is in equilibrium, the net force is zero, along x-axis :10 + 10√2 cos45 = P sinθ .............(1)Along y-axis 10 + P cosθ = 10√2 sin45.................(2)From (2) cosθ = 0 ⇒ θ = 900 and P = 20 NTalk to our academic expert!
