When the angle between the two vectors are not a multiple of 180 degrees.
The condition is the two vectors are perpendicular to each other.
To add two vectors that aren't parallel or perpindicular you resolve both of the planes displacement vectors into "x' and "y" components and then add the components together. (parallelogram technique graphically)

You get a third vector.
The law is used to add vectors to find the resultant of two or more vectors acting at a point.

One common reason why you need to do this is to add vectors. If you have two different vectors, and want to add them - algebraically, of course - then you first need to separate them into components. After you do that, you can easily add the components together.
You can add the vectors graphically - join them head-to-tail. Or you can solve them algebraically: you can separate them into components, and add the components.
No.
Two vectors with unequal magnitudes can't add to zero, but three or more can.
No. Vectors add at rightangle bythe pythagoran theorem: resultant sum = square root of (vector 1 squared + vector 2 squared)
Sure, if the two vectors point in the same direction.When we need the sum of magnitudes of two vectors we simply add the magnitudes, but to get the magnitude of the sum of these two vectors we need to add the vectors geometrically.Formula to find magnitude of the sum of these two vectors is sqrt[ |A|2 +|B|2 +2*|A|*|B|*cos(z) ] where |A| and |B| are magnitudes of two A and B vectors, and z is the angle between the two vectors.Clearly, magnitude of sum of two vectors is less than sum of magnitudes(|A| + |B|) for all cases except when cos(z)=1(for which it becomes = |A| + |B| ). Cos(z)=1 when z=0, i.e. the vectors are in the same direction(angle between them is 0).Also if we consider addition of two null vectors then their sum is zero in both ways of addition.So, we get two caseswhen the two vectors are in same direction, andwhen the two vectors are null vectors.In all other cases sum of magnitudes is greater than magnitude of the sum of two vectors.
