Question

The springs shown in the figure are all upstretched in the beginning when a man starts pulling the block. The man exerts a constant force F on the block.

A. the amplitude of oscillation is `((K_(2)+K_(3))F)/(K_(1)K_(2)+K_(2)K_(3)+K_(3)K_(1))`
B. the oscillation frequency is `(1)/(2pi)[(K_(1)K_(2)+K_(2)K_(3)+K_(3)K_(1))/(M(K_(2)+K_(3)))]^(1//2)`
C. the amplitude of oscillation is `(2(K_(2)+K_(3))F)/(K_(1)K_(2)+K_(2)K_(3)+K_(3)K_(1))`
D. the oscillation frequency is `(1)/(pi)[(K_(1)K_(2)+K_(2)K_(3)+K_(3)K_(1))/(M(K_(2)+K_(3)))]^(1//2)`
