The amplitude of vibration of a particle is given by 
where 
and c are positive. The condition for a single resonant frequency is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
For resonance amplitude must be maximum which is possible only when the denominator of expression is zero i.e. 
For a single resonant frequency, b 2 = 4ac.
