Rod is massless and of length\[\ell \]. Find angular frequency \[\omega \](in\[{{s}^{-1}}\]) of small oscillation of the block of mass m, the hinge is frictionless. \[{{k}_{1}},{{k}_{2}},{{k}_{3}}\]are spring constants of the shown springs. Ignore gravity.\[\left( {{k}_{1}}={{k}_{2}}=10N/m,{{k}_{3}}=\frac{15}{4}N/m,\,\,m=250gm \right)\]
