NEET Physics Equilibrium of Forces MCQ Question
In a free-body diagram for a point P, which of the following equations correctly represents the condition for equilibrium with tensions T1, T2, and a horizontal force of 50 N, given that T2 = 60 N?
T1 cos θ = 60 N and T1 sin θ = 50 N
T1 sin θ = 60 N and T1 cos θ = 50 N
T1 = 60 N and T2 = 50 N
T1 cos θ = 50 N and T1 sin θ = 60 N
Correct Answer
Detailed Explanation
For equilibrium, the horizontal and vertical components of the resultant force must vanish separately. This leads to equations T1 cos θ = T2 = 60 N and T1 sin θ = 50 N.
