You are provided with three retort stands, a pendulum bob, drawing board, stop-watch and other necessary apparatus. Using the diagram above as a guide, carry out the following instructions:

(i) Fix the drawing paper on the drawing board and hold the board with two clamps such that its vertical.
(ii) Suspend the pendulum bob such that it hangs freely in front of the drawing appear.
(iii) Draw a line RP representing the rest position of the pendulum string and mark the position P of the centre of the pendulum bob at rest.
(iv) Displace the pendulum bob to one side in a plan parallel to the drawing board.
(v) Mark the new position p¹ of the centre of the bob.

(vi) Measure and record the perpendicular distance, d of pi from the line RP.
(vii) Evaluate and record d2
(viii) Measure and record the vertical height h of p¹ above P.
(ix) Evaluate G =d2/h
(x) Repeat the procedure for four other oppositions of p.

(xi) tabulate your readings.
(xii) remove the drawing board so that the pendulum bob can swing freely. 
(xiii) Set the pendulum bob oscillating through a small amplitude and determine the time t for 20 oscillations.
(xiv) determine and record the period T.
(xv) plot a graph with G on the vertical axis and h on the horizontal axis, starting both axes from the origin (0, 0).
(xvi) Determine the intercept 1 on the horizontal axis.

(vi) Remove the prism and the pins at P3 and P4 Draw a line to join P3 and P4.
(vii) Produce line P4P3 to meet the line DC at O. Draw a line to join NO.
(viii) Measure and record the values of MO and NO.
(ix) Evaluate ф =  and  cos θ.
(x) Repeat the procedure for four other values of θ – 65°, 55°, 45° and 35°. In each case, evaluate ф and cos θ
(xi) Tabulate your reading
(xii) Plot a graph with cos θ on the vertical axis and ф on the horizontal axis.
(xiii) Determine the slope, s, of the graph.
(xiv) Sate two precautions taken to ensure accurate results.
