On Fig. 2.1, draw the force-extension graph for the spring for loads up to 120 N.
(b(ii))[2]
Calculate the value of the spring constant $k$ for the spring.
(c)[2]
Suggest and explain why it does not read 140 N.
Worked solution & mark scheme
This 6-mark question has a full step-by-step worked solution and mark scheme. One marking point: “Spring extension is directly proportional to load/force/weight OR F = ke (e = extension)” …
