Threevectors vecA, vecB, vecB are shown in the figure. Find angle between (i)vecA and vecB (ii)vecB and vecC (iii)vecA and vecC. |
Answer» SOLUTION :To find the angle between two vectors we connect the tails of the two vectors. We can SHIFT the vectors PARALLEL to themselves such that tails of `vecA, VECB and VECC` are connected as shoown in figure.  Now we observe that angle between `vecA and vecB` is `60^(@),vecB and vecC` is `15^(@)` and between `vecA and vecC` is `75^(@)` |
