Question
Complete the table below
Load (N)  0  1  2  3 
Length (cm)  15.2  16.2  17.3  18.6 
Extension (cm)  0  1.0  ________  3.4 
Find missing figure in the table?
Choices
Choice (4)  Response  

a.  17.3 

b.  2.1 

c.  18.3 

d.  17.4 

Answer
b.Explanation
Here due to load extension of rubber is taking places.
From first column, when load is zero, extension is zero so original length is 15.2.
Now as load increases, the length of rubber extended. Therefore for load 2 N, the length measured is 17.3 cm.
And original length is 15.2
So missing figure in extension of length is,
