1Section A Bahagian A [28 marks] [28 markah] Answer all questions in this section Jawab semua soalan dalam bahagian ini. 1 A student carries out an experiment to investigate the relationship between the extension of spring, x and weight of load, W. The apparatus is set up as shown in Diagram 1.1. Seorang pelajar menjalankan eksperimen untuk mengkaji hubungan antara pemanjangan spring, x dan berat pemberat, W. Susunan alat radas ditunjukkan dalam Rajah 1.1. Spring Spring Weight Pemberat Ruler Pembaris Diagram 1.1 Rajah 1.1 The spring will extend when a weight is hung at one end. The length of spring, l is recorded. Spring akan memanjang apabila beban digantung pada hujungnya. Panjang spring, l direkodkan. 4531/3 © 2015 SULIT 4. for W = 10 N.2 Diagram 1. .2 Rajah 1.
