A block is placed on a frictionless horizontal table. The mass of the block is m and springs are attached on either side with force constants ` K_(1) and K_(2)` . If the block is displaced a little and left to oscillate, then the angular frequency of oscillation will be

Options

A. `((K_(1)+ K_(2))/(m))^(1//2`
B. `[(K_(1)+ K_(2))/(m(K_(1)+ K_(2))]]^(1//2)`
C. `[(K_(1)+ K_(2))/((K_(1)-K_(2))m]]^(1//2)`
D. `[(K_(1)K_(2))/((K_(1)+K_(2))m)]^(1//2)`

Answer

A
