One end of the rope is fixed to vertical wall and other end pulled by horizontal force of 20 N. The shape of flexible rope is shown in figure. The mass of rope is-
Text Solution
Verified by ExpertsThe correct answer is:
C
T sin θ = 20
T cos θ = W
tan θ = 
W = 20 cot θ
W = 20 cot 30 0
W = 20 
= 20 × 1.732
Weight W = 34.64 N
mass ‘m’ = 
= 3.5 kg.
