A thin uniform rod of length \(L\) is resting against a wall and the floor as shown in the figure. Its lower end \(A\) is pulled towards left with a constant velocity \(v\). Then the downward velocity \(v^{\prime}\) of the other end \(B\) when the rod makes an angle \(\theta\) with the floor is
- A v
- B \(v \cos \theta\)
- C \(v \sin \theta\)
- D \(v \cot \theta\)
Answer & Solution
Correct Answer
(D) \(v \cot \theta\)
Step-by-step Solution
Detailed explanation
According to the question, Given, length of the uniform rod \(=L\) the angle between rod and floor \(=\theta\) the angle between wall and floor \(=90^{\circ}\) Let the distance between point \(O\) to \(A\) is \(x\) and the distance between point \(O\) to \(B\) is \(y\). Now, By…
