(a) A student is provided with five 20g masses, a meter ruler, a spring with a pointer, a stand, a boss and a clamp.
(i) In the space provided, sketch a labeled
diagram of the set up that may be used in order to verify Hook’s law using these apparatus.
(ii) State two measurements that should be recorded in order to plot a suitable graph so as to verify Hooke’s law.
(iii)Describe how the measurements made in (ii) can be used to determine the spring constant.
(b) A helical spring stretches by 0.6cm when supporting a weight of 40g. Determine the extension when the same spring supports a weight of 65g.
