Answer:
Given:
5 vectors have been provided in the form of 2 triangles.
To find:
Concept:
First assign names to the triangle , It will be helpful in identify of vectors. Let the Left triangle be X and Right triangle be Y.
Calculation:
1st question:
Let's consider Triangle Y :
Vectors A , B , E are all directed cyclically , so we can say that :
2nd question:
Now consider Triangle X , we can see that :
3rd question :
In this, we need to consider both the triangles.
And we need to use the equations derived in earlier answers :
From the above figure, the following interferences are ovious.
