(a) Apabila suatu beban berjisim 0.4 kg digantung kepada hujung suatu spring, pemanjangan spring,
x ialah 6 cm. Panjang spring, l ialah 10 cm. Rajah di bawah menunjukkan beberapa susunan spring
yang dibina daripada beberapa spring yang serupa. Dalam setiap susunan spring, tunjukkan jumlah
panjang sistem spring itu.
When a mass of 0.4 kg is hung on the end of a spring, extension of the spring is 6 cm. The length of the spring is l = 10 cm. The
diagram below shows several spring arrangements constructed from several similar springs. In each spring arrangement, show
the total length of the spring system.
