Question

A mass m attached to a spring A has a frequency of 3 Hz and a spring B has a frequency of 4 Hz. When both the springs are connected as shown, find the frequency (in Hz) of oscillation.

  1. 3    
  2. 4    
  3. 5    
  4. none    

The correct answer is: 5


    Parallel combination T to the power of 2 end exponent equals T subscript 1 end subscript to the power of 2 end exponent plus T subscript 2 end subscript to the power of 2 end exponent rightwards double arrow 3 to the power of 2 end exponent plus 4 to the power of 2 end exponent equals 5
