Two springs are joined & attached to a mass of 16 kg. The system is then suspended vertically from a rigid support. The spring constants of the two springs are — `K_(1)` & `K_(2)` respectively. The period of vertical oscillations of the system will be -

Options

A. `(1)/(8pi) sqrt(K_(1)+K_(2))`
B. `8pi sqrt((K_(1)+K_(2))/(K_(1)K_(2)))`
C. `(pi)/(2) sqrt(K_(1)-K_(2))`
D. `(pi)/(2) sqrt((K_(1))/(K_(2)))`
