Two identical pendulums are tied from the same rigid support. One is tied horizontally. The other is released when they are making the same angle θ θ with the vertical.
Text Solution
Verified by ExpertsThe correct answer is:
D
T 1 cos θ θ = mg
T 1 = mg/cos θ θ
T 2 = mg cos θ θ
T 1 /T 2 = 1/cos 2 θ θ
= sec 2 θ θ
