Q.

The kinetic energy of a simple harmonic oscillator is oscillating with angular frequency of 176 rad/s. The frequency of this simple harmonic oscillator is ______ Hz.

[take π=227]   [2026]

1 14  
2 176  
3 28  
4 88  

Ans.

(1)

ω=176 rad/sec

fk=ω2π=1762×22×7

=17644×7

=4×7=28 Hz

So frequency of oscillator

f=k2=14 Hz
