If a, b, c, and d are coplanar Vectors, then (a × b) × (c × d) =
A
a
B
b
C
0
D
None of these
Correct Option:
C
Explanation
Since a, b, c, and d are coplanar, both a × b and c × d are perpendicular to the same plane. Therefore, these two cross products are parallel or antiparallel. The cross product of parallel vectors is zero, so (a × b) × (c × d) = 0.
