Mark (√) against the correct answer in the following:
If θ is the angle between two unit vectors 
and 
then 
Given 
and 
are unit vectors
Let θ be the angle between them.
Asking us to find the value of 
Let this value de T
⇒T=
Squaring on both the sides
T2 =
T2=
T2=
T2=
T2=
T2=
T2=
can be written as 
⇒ T2=
= T2=
T2=
⇒T=
