When a body oscillates with its natural frequency then its vibration is called

What is natural frequency of oscillation of a system?

What is the natural frequency of an LC oscillator?

If a body oscillates at the angular frequency (omega_(d)) of the driving force, then the oscillations are called

An inductor of inductance 2 mH is connected across a charged capacitor of capacitance 5 mu F and the L-C circuit is set oscillating at its natural frequency. What is the natural angular frequency of its oscillations?

(A) : Resonance is a special case of forced vibration in which the natural frequency of vibrations of the body is the same as the impressed frequency and the amplitude forced vibration is maximum. (R) The amplitude of forced vibration of a body increases with an increase in the frequency of the externally impressed periodic force.

Explain (i) natural oscillation (ii) natural frequency.

A metallic bar clamped at its middle point vibrates with a frequency v when it is rubbed at one end. If its length is doubled, what will be its natural frequency of vibration ?
