Given that p=9i+12j and q=-6i-8j. Evaluate |p-q|-{|p|-|q|}

Step-by-step explanation:

First let's find the value of 'p-q':

To find |p-q| (module of 'p-q'), we can use the formula:

Where 'a' is the coefficient of 'i' and 'b' is the coefficient of 'j'

So we have:

Now, we need to find the module of p and the module of q:

Then, evaluating |p-q|-{|p|-|q|}, we have:
