Two masses of mass m each are fixed at a separation distance of `2d`. A small mass `m_(s)` placed midway, when displaced slightly, starts oscillating. Then : A. Frequency of simple harmonic motion is given by `1/(2pi)sqrt((4Gm)/(d^(3)))`B. Frequency of simple harmonic motion is given by `1/(2pi)sqrt((2Gm)/(d^(3)))`C. Accleration of the mass `m_(s)`, is given by `(Gm)/(d^(2))`D. Time period of vibration is `2pisqrt((GM)/((2d)^(3))`
