When a mass m is connected individually to two springs S1 and S2 , the oscillation frequencies are ν 1 and ν 2 . If the same mass is attached to the two springs as shown in Fig. , the oscillation frequency would be
Options:
(a) `ν_ 1 + ν_ 2` .
(b) `sqrt(ν_ 1 ^2+ ν_ 2^2)`.
(c) `(1/ν_ 1 +1/ ν_ 2)^(-1)`.
(d) `sqrt(ν_ 1 ^2 - ν_ 2^2)`
