Two springs of spring constant $k_{1}$ and $k_{2}$ are joined in series. The effective spring constant of the combination is given by:NEET 2004

Options:

Answer:

Solution:

When the spring joined in series the total extension of spring is: $\Rightarrow y = y_{1} + y_{2} = \frac{- F}{k _{1}} - \frac{F}{k _{2}} \Rightarrow y = - F [\frac{1}{k _{1}} + \frac{1}{k _{2}}] ∴ Spring constant k = \frac{k _{1} k _{2}}{k _{1} + k _{2}}$
