Question
Let
and
be three vectors each of magnitude √2 and the angle between each pair of them is
. If
is a nonzero vector perpendicular to
and
and
is a nonzero vector perpendicular to
and
, then
. If Options
A.
B.
C.
D.
Solution
Given that
and 

∴
(Option B is correct)
(Option A is correct)

and
= - λμ(1 - 1 - 2 + 1)
= - λμ
(Option C is correct)

∴ (A, B, C) are correct.
∴
and
= - λμ(1 - 1 - 2 + 1)
= - λμ
∴ (A, B, C) are correct.
