Advanced Science Primary 6 Interactions

Two identical springs, A and B, are hung side-by-side. A 50g weight is hung on Spring A and a 100g weight is hung on Spring B. If Spring A extends by 4 cm, what is the extension of Spring B?

A 8 cm
B 4 cm
C 2 cm
D 12 cm
Show Worked Solution

Worked Solution

Step 1: Extension is proportional to weight for identical springs. Step [2-9]: 100g is twice the weight of 50g. Step [2-9]: Therefore, the extension is 4 cm x 2 = 8 cm.

Correct answer: 8 cm
