Questions
The amplitude of vibration of a particle is given by where and c are positive. The condition for a single resonant frequency is
detailed solution
Correct option is A
For resonance amplitude must be maximum which is possible only when the denominator of expression is zero i.e. aω2−bω+c=0⇒ω=-b±b2−4ac2aFor a single resonant frequency, b2 = 4ac.Talk to our academic expert!
