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 the vectors parallel to themselves such that tails of `vecA,vecB` and `vecC` are connected as shown in figure.

Now we observe that angle between `vecA` and `vecB`
is `60^(@),vecB` and `vecC 15^(@)` between `vecA` and `vecC` is `75^(@)`
