JEE Advanced Level Test: Vector Algebra- 2 - Question 17   is equal to

Detailed Solution for JEE Advanced Level Test: Vector Algebra- 2 - Question 17

Solution :- [a×b b×c c×a]

= (a×b) . [(b×c) * (c×a)]

= (a×b) [(b×c) . a(c) - (b×c) . c]

= (a×b) [(b×c) . a(c) - 0]

= [(a×b) . c] [(b×c) . a]

= [a b c] [(b c a]

= - [a b c] [(a c b]

= [a b c] [(a b c ]   => [a b c]^2
