A uniform rod of length \(1.8 \mathrm{~m}\) suspended by an end is made to undergo small oscillations. Find the length of the simple pendulum having the mass and time period equal to that of the rod.
- A \(3.6 \mathrm{~m}\)
- B \(1.2 \mathrm{~m}\)
- C \(2.4 \mathrm{~m}\)
- D \(4.2 \mathrm{~m}\)
Answer & Solution
Correct Answer
(B) \(1.2 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
Given, length of the rod, \(l=1.8 \mathrm{~m}\) Time period of the oscillation of uniform rod with length l piwoted at one end is given by \(T=2 \pi \sqrt{\frac{I}{m g R}}\) where, \(R\) is the distance of the point of pivot to the centre of the gravity and \(I\) is moment of…
