When three springs of spring constants k1, k2, k3 connected in parallel, then the resultant spring constant is ……………………
A. K = k1 + k2 + k3
B. \(\frac{1}{K}\) = \(\frac { 1 }{ k_{ 1 } } +\frac { 1 }{ k_{ 2 } } +\frac { 1 }{ k_{ 3 } } \)
C. K = \(\frac { 1 }{ k_{ 1 } } +\frac { 1 }{ k_{ 2 } } +\frac { 1 }{ k_{ 3 } } \)
D. K = k1 – k2 – k3
