Question

What will be the force constant of the spring system shown in figure?

  1. fraction numerator k subscript 1 end subscript over denominator 2 end fraction plus k subscript 2 end subscript    
  2. open square brackets fraction numerator 1 over denominator 2 k subscript 1 end subscript end fraction plus fraction numerator 1 over denominator k subscript 2 end subscript end fraction close square brackets to the power of negative 1 end exponent    
  3. fraction numerator 1 over denominator 2 k subscript 1 end subscript end fraction plus fraction numerator 1 over denominator k subscript 2 end subscript end fraction    
  4. open square brackets fraction numerator 2 over denominator k subscript 1 end subscript end fraction plus fraction numerator 1 over denominator k subscript 2 end subscript end fraction close square brackets to the power of negative 1 end exponent    

The correct answer is: open square brackets fraction numerator 1 over denominator 2 k subscript 1 end subscript end fraction plus fraction numerator 1 over denominator k subscript 2 end subscript end fraction close square brackets to the power of negative 1 end exponent


    Two springs each of spring constant k subscript 1 end subscript in parallel, given equailvalent spring constant of 2 k subscript 1 end subscript and this is in series with spring of constant k subscript 2 end subscript, so equivalent spring constant,
    k equals open parentheses fraction numerator 1 over denominator k subscript 2 end subscript end fraction plus fraction numerator 1 over denominator 2 k subscript 1 end subscript end fraction close parentheses to the power of negative 1 end exponent

    A mass of 2.0 kg is put on a flat pan attached to a vertical spring fixed on the ground as shown in the figure. The mass of the spring and the pan is negligible. When pressed slightly and released the mass executes slightly and released the mass executes a simple harmonic motion. The spring constant is 200 blank N m to the power of negative 1 end exponent. What should be the minimum amplitude of the motion, so that the mass gets detached from the pan? (Take g=10 m s to the power of negative 2 end exponent )
