Question

Fish are hung on a spring scale to determine their mass (most fishermen feel no obligation to truthfully report the mass). What is the force constant of the spring in such a scale if it the spring stretches 8.50 cm for a 8.1 kg load

    Answer:

    k = 933.88 N/m

    Explanation:

    Given that,

    The mass of a load, m = 8.1 kg

    The displacement in the spring, x = 8.5 cm

    We need to find the force constant of the spring. We know that Hooke’s law is given by :

    F = -kx

    Also,

    F = mg (Force due to its weight)

    So,

    k=\dfrac{mg}{x}\\\\k=\dfrac{8.1\times 9.8}{0.085}\\\\k=933.88\ N/m

    So, the force constant of the spring is equal to 933.88 N/m.
