Three vectors vecA, vecB, vecC are shown...

Three vectors `vecA, vecB, vecC` are shown in the figure. Find angle between (i) `vecA` and `vecB` (ii) `vecB` and `vecC` , (iii) `vecA` and `vecC`

Text Solution

Verified by Experts

To find the angle between two vectors we connect the tails of the two vectors. We can shift (such that tails of `vecA, vecB"and " vecC `are connected as shown in figure.
Now we can easily observe that angle between `vecA"and " vecB "is " 60^(@), vecB "and " vecC ` is `15^(@)` and between `vecA " and "vecC`is `75^(@)`
