An \(L-\) shaped object, made of thin rods of uniform mass density, is suspended with a string as shown in figure. If \(AB = BC\), and the angle made by \(AB\) with downward vertical is \(\theta\) then
- A \(\tan \,\theta = \frac{1}{{2\sqrt 3 }}\)
- B \(\tan \,\theta = \frac{1}{3}\)
- C \(\tan \,\theta = \frac{2}{{\sqrt 3 }}\)
- D \(\tan \,\theta = \frac{1}{2}\)
Answer & Solution
Correct Answer
(B) \(\tan \,\theta = \frac{1}{3}\)
Step-by-step Solution
Detailed explanation
Lets considered mass of each rod is m for stable equilibrium the torque about point \(O\) should be zero. Torque balance about \(O\)…
