Answer
given,
length of slender rod =80 cm = 0.8 m
mass of rod = 0.39 Kg
mass of small sphere = 0.0200 kg
mass of another sphere weld = 0.0500 Kg
calculating the moment of inertia of the system
![I = \dfrac{ML^2}{12}+\dfrac{m_1L^2}{4}+\dfrac{mL^2}{4}](https://tex.z-dn.net/?f=I%20%3D%20%5Cdfrac%7BML%5E2%7D%7B12%7D%2B%5Cdfrac%7Bm_1L%5E2%7D%7B4%7D%2B%5Cdfrac%7BmL%5E2%7D%7B4%7D)
![I = \dfrac{0.39\times 0.8^2}{12}+\dfrac{0.02\times 0.8^2}{4}+\dfrac{0.05\times 0.8^2}{4}](https://tex.z-dn.net/?f=I%20%3D%20%5Cdfrac%7B0.39%5Ctimes%200.8%5E2%7D%7B12%7D%2B%5Cdfrac%7B0.02%5Ctimes%200.8%5E2%7D%7B4%7D%2B%5Cdfrac%7B0.05%5Ctimes%200.8%5E2%7D%7B4%7D)
![I =0.032\ kg.m^2](https://tex.z-dn.net/?f=I%20%3D0.032%5C%20kg.m%5E2)
using conservation of energy
![\dfrac{1}{2}I\omega^2 = (m_1-m_2)g\dfrac{L}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7DI%5Comega%5E2%20%3D%20%28m_1-m_2%29g%5Cdfrac%7BL%7D%7B2%7D)
![\omega=\sqrt{\dfrac{(m_1-m_2)gL}{I}}](https://tex.z-dn.net/?f=%5Comega%3D%5Csqrt%7B%5Cdfrac%7B%28m_1-m_2%29gL%7D%7BI%7D%7D)
![\omega=\sqrt{\dfrac{(0.05-0.02)\times 9.8 \times 0.8}{0.032}}](https://tex.z-dn.net/?f=%5Comega%3D%5Csqrt%7B%5Cdfrac%7B%280.05-0.02%29%5Ctimes%209.8%20%5Ctimes%200.8%7D%7B0.032%7D%7D)
![\omega=2.71 \rad/s](https://tex.z-dn.net/?f=%5Comega%3D2.71%20%5Crad%2Fs)
we know,
v = r ω
![v = \dfrac{L}{2} \times 2.71](https://tex.z-dn.net/?f=v%20%3D%20%5Cdfrac%7BL%7D%7B2%7D%20%5Ctimes%202.71)
![v = \dfrac{0.8}{2} \times 2.71](https://tex.z-dn.net/?f=v%20%3D%20%5Cdfrac%7B0.8%7D%7B2%7D%20%5Ctimes%202.71)
v = 1.084 m/s
