Ravi hung four different weights on the same spring and measured its extension. Which graph correctly shows the relationship between the weight added and the extension of the spring?

A A horizontal line
B A straight line starting from a point above the origin
C A straight line starting from the origin
D A curved line decreasing downwards

Worked Solution

Step 1: Extension is the increase in length (Total length - Original length). Step 2: Within the elastic limit, extension is directly proportional to the weight added. Step 3: Therefore, the graph should be a straight line starting from zero (the origin).

Correct answer: A straight line starting from the origin
