A frictionless inclined surface having inclination $$300$$ 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, tension in the spring reduces to zero. On releasing the mass now, its angular frequency of oscillations will be:

Question

A frictionless inclined surface having inclination $$300$$ 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, tension in the spring reduces to zero. On releasing the mass now, its angular frequency of oscillations will be:

In equilibrium, Mg $$sin$$ $$30o=$$$$kx$$⇒             $$k=Mg$$ son $$30ox$$                  $$k=2.5$$×$$9.8$$×$$122.5$$×$$10-2=4.9$$×$$102$$ $$N/m$$                  ω$$=km=4.9$$×$$1022.5=14$$

A frictionless inclined surface having inclination $30^{0}$ 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, tension in the spring reduces to zero. On releasing the mass now, its angular frequency of oscillations will be:
