A smooth inclined plane having angle of inclination $$of300$$ with the horizontal has a $$2.5$$ kg mass held by a spring which is fixed at the upper end. If the mass is taken $$2.5$$ cm up along the surface of the inclined plane, the tension in the spring reduces to zero, If the mass is now released, the angular frequency of oscillation is

A smooth inclined plane having angle of inclination $$of300$$ with the horizontal has a $$2.5$$ kg mass held by a spring which is fixed at the upper end. If the mass is taken $$2.5$$ cm up along the surface of the inclined plane, the tension in the spring reduces to zero, If the mass is now released, the angular frequency of oscillation is
