A spring has an original length of 10 cm. When a 100g weight is hung on it, the length becomes 12 cm. What will be the length of the spring if a 200g weight is hung on it (assuming the elastic limit is not reached)?

Worked Solution
Step 1: Calculate the extension for 100g: 12cm - 10cm = 2cm.
Step 2: For 200g (double weight), the extension doubles: 2cm x 2 = 4cm.
Step 3: Add the extension to the original length: 10cm + 4cm = 14cm.
Correct answer: 14 cm
