Question
The apparatus is to be set up for the candidates as shown in Fig. 1.1. The spring is to be suspendedfrom the clamp, supported by a boss and stand. The spring must be sufficiently high above thelaboratory bench so that when the 1.00 N load is suspended from the spring, the bottom of theload is above the surface of the bench.3. The metre rule (supported by the clamp, boss and stand) must be near to, but not touching, thespring. The 100 cm end of the metre rule must be touching the bench
Solution
Sure, here are the steps to set up the apparatus:
-
Start by setting up the boss and stand on the laboratory bench. Make sure it is stable and secure.
-
Attach the clamp to the boss and stand. Ensure it is tightened and secure.
-
Suspend the spring from the clamp. Make sure it is high enough above the bench so that when the 1.00 N load is suspended from it, the bottom of the load is still above the surface of the bench.
-
Next, set up another clamp, boss and stand for the metre rule. This should be near the spring but not touching it.
-
Place the metre rule in the clamp with the 100 cm end touching the bench. Make sure the rule is secure and straight.
-
Finally, attach the 1.00 N load to the spring. Check that the bottom of the load is above the surface of the bench.
Remember to handle all equipment with care to ensure accurate results and to maintain safety in the laboratory.

Q 1: A student is finding the weight of a metre rule using the apparatus shown in Figure 1. Figure 1 (not to scale) He places the load P = 1.00 N on the metre rule at the 5.0 cm mark. He places the metre rule on the pivot at the 45.0 cm mark. He places load Q = 0.80 N on the rule and adjusts its position so that the metre rule is as near as possible to being balanced. He measures the distance x (between the centre of load P and the pivot) the distance y (between the centre of load Q to the pivot) He repeats the procedure, placing the load P at the 10.0 cm mark, at the 15.0 cm mark, at the 20.0 cm mark and at the 25.0 cm mark. The readings are shown in Table. Table 1 x ( ) y ( ) A = P x ( ) B = Q y ( ) 40.0 42.5 35.0 36.0 30.0 30.0 25.0 24.0 20.0 17.5 (i) In the table 1: (a) Complete the column headings/units.

Y = [1] (iv) Calculate the weight W of the metre rule using the equation W = Y/z , where z = 5.0 cm. W = [1] 6 (v) Suggest one practical reason why it is difficult to obtain exact results with this experiment. [1] (vi) The student uses an accurate electronic balance to obtain a second value for the weight of the metre rule. weight obtained on the balance = 1.24 N State and justify whether the two values for the weight agree within the limits of experimental accuracy.

A helical spring is hung from the edge of a bench top, as shown. Before the load is hung on the spring, the pin points to the 29.8 cm mark on the metre rule.When a load of 5.5 N is hung on the spring, the pin points to 62.8 cm. Calculate the the spring constant.
