On Fig. 2.1, identify and label the section where the spring obeys Hooke’s law.
(b(ii))[2]
Calculate the spring constant, $k$.
(b(iii))[2]
Calculate the spring’s length when a load of $8.5\text{ N}$ is applied to it.
(c)[2]
Calculate the mass of the object.
Worked solution & mark scheme
This 8-mark question has a full step-by-step worked solution and mark scheme. One marking point: “The extension is directly proportional to the load, provided the elastic limit is not exceeded.” …
