TS EAMCET · Physics · Oscillations
Three masses \(700 \mathrm{~g}, 500 \mathrm{~g}\) and 400 \(\mathrm{g}\) are suspended at the end of a spring shown in figure and are in equilibrium. When the \(700 \mathrm{~g}\) mass is removed, the system oscillates with a time period of \(3 \mathrm{~s}\). If \(500 \mathrm{~g}\) mass is further removed, then it will oscillate with a period of
- A 1s
- B 2s
- C 3s
- D \(\sqrt{\frac{12}{5}} \mathrm{~s}\)
Answer & Solution
Correct Answer
(B) 2s
Step-by-step Solution
Detailed explanation
Time-period of oscillations, \(T=2 \pi \sqrt{\frac{m}{k}}\) where, \(m=\) mass of the oscillating system and \(\quad k=\) spring constant. Case I \(700 \mathrm{~g}\) mass is removed, then \(m=500 \mathrm{~g}+400 \mathrm{~g}=900 \mathrm{~g}=0.9 \mathrm{~g}\) So,…
