AP EAMCET · PHYSICS · Oscillations
A body of mass \(4.9 \mathrm{~kg}\) hangs from a spring and oscillates with a period \(0.5 \mathrm{~s}\). On the removal of the body, the spring is shortened by (take, \(g=10 \mathrm{~ms}^{-2}, \pi^2=10\) )
- A \(6.3 \mathrm{~m}\)
- B \(0.63 \mathrm{~m}\)
- C \(6.25 \mathrm{~cm}\)
- D \(63 \mathrm{~cm}\)
Answer & Solution
Correct Answer
(C) \(6.25 \mathrm{~cm}\)
Step-by-step Solution
Detailed explanation
Given that, mass of body, \(m=4.9 \mathrm{~kg}\) Time period of oscillation of spring, \(T=0.5 \mathrm{~s}\) Acceleration due to gravity, \(g=10 \mathrm{~m} / \mathrm{s}^2\) and \(\pi^2=10\) We know that, time period of spring \(T=2 \pi \sqrt{\frac{m}{k}}\) By squaring on both…
