Candidates answer on the Question Paper.
Additional Materials: As listed in the Confidential Instructions.
READ THESE INSTRUCTIONS FIRST
Write your centre number, candidate number and name on all the work you hand in.
Write in dark blue or black pen.
You may use an HB pencil for any diagrams or graphs.
Do not use staples, paper clips, glue or correction fluid.
DO NOT WRITE IN ANY BARCODES.
Answer both questions.
You will be allowed to work with the apparatus for a maximum of one hour for each question.
You are expected to record all your observations as soon as these observations are made, and to plan the
presentation of the records so that it is not necessary to make a fair copy of them.
You are reminded of the need for good English and clear presentation in your answers.
Electronic calculators may be used.
You may lose marks if you do not show your working or if you do not use appropriate units.
Additional answer paper and graph paper should be used only if it becomes necessary to do so.
At the end of the examination, fasten all your work securely together.
The number of marks is given in brackets [ ] at the end of each question or part question.

You may not need to use all of the materials provided.
1 In this experiment, you will investigate a pendulum with a mass fixed at each end.
(a) • Assemble the apparatus with the nail passing through the third hole from C, as shown in
Fig. 1.1.
• Ensure that the nail is held securely in the clamp.

• The distance between the nail and C is x, as shown in Fig. 1.1.
Measure and record x.
x = .................................................... cm [1]
(b) • Push the bottom of the strip horizontally through a distance of approximately 5 cm.
Release the strip so that it oscillates.
• Determine the period T of these oscillations.
T = ....................................................... s [2]

(c) Change x by positioning the nail in a different hole and repeat (b). Repeat until you have six
sets of values of x and T.
