A simple pendulum oscillates with an angular amplitude \(\theta\). If the maximum tension in the string is 4 times the minimum tension then the value of \(\theta\) is
- A \(\cos ^{-1}(0 \cdot 75)\)
- B \(\cos ^{-1}(0 \cdot 5)\)
- C \(\sin ^{-1}(0 \cdot 5)\)
- D \(\sin ^{-1}(0 \cdot 75)\)
Answer & Solution
Correct Answer
(B) \(\cos ^{-1}(0 \cdot 5)\)
Step-by-step Solution
Detailed explanation
\(T_{max} = mg(3 - 2\cos\theta)\) \(T_{min} = mg\cos\theta\)
