Question

A pendulum of mass m and length L is connected to a spring as shown in figure. If the bob is displaced slightly from its mean position and released, it performs simple harmonic motion .The angular frequency of the oscillation of bob is

  1. square root of fraction numerator g over denominator L end fraction end root    
  2. square root of fraction numerator k h to the power of 2 end exponent plus m g L over denominator m L to the power of 2 end exponent end fraction end root    
  3. square root of fraction numerator 3 g over denominator L end fraction end root    
  4. square root of fraction numerator k h to the power of 2 end exponent over denominator text end text m L to the power of 2 end exponent end fraction end root    

The correct answer is: square root of fraction numerator k h to the power of 2 end exponent plus m g L over denominator m L to the power of 2 end exponent end fraction end root
