Problem

When two identical ideal springs, each with spring constant

k

, are connected in parallel and stretched by the same amount, what is the effective spring constant

k_{\text{eff}}

of the combination? a)

k_{\text{eff}} = k

k_{\text{eff}} = \sqrt{2}\,k

k_{\text{eff}} = 2k

k_{\text{eff}} = \dfrac{k}{2}
