Answer all questions in this section.
0 1 A simple pendulum performs oscillations of period T in a vertical plane.
Figure 1 shows views of the pendulum at the equilibrium position and at the instant of
release. Figure 1 also shows a rectangular card marked with a vertical line.
Figure 1
0 1 . 1 The card can be used as a fiducial mark to reduce uncertainty in the measurement
of T.
Annotate Figure 1 to show a suitable position for the fiducial mark.
Explain why you chose this position.

Figure 2 shows an arrangement used to determine the maximum amplitude that can
be considered to be small, by investigating how T varies with amplitude.
Figure 2
Describe a suitable procedure to determine AR, the amplitude of the pendulum as it is
released.
You may add detail to Figure 2 to illustrate your answer.
