Question

Two bodies of masses \(1\,kg\) and \(4\,kg\) are connected by a spring of spring constant \(K=5\,N\,m^{-1}\). Find the time period of oscillation.

• A. \(\frac{4\pi}{5}\,s\)
• B. \(\frac{2\pi}{5}\,s\)
• C. \(\pi\,s\)
• D. \(2\pi\,s\)

Hint:

For two masses connected by a spring, always use reduced mass \(\mu=\frac{m_1m_2}{m_1+m_2}\) before applying the SHM time-period formula.

Answer 1

The Correct Option is A
