There are 6 vectors: a, b, c, d, e, f. Simply the following expression: [ a(b . c) X (e . f)d ] X [ a – d ].‘X’ represents cross product while ’.‘ represents dot product. Vectors a & d are perpendicular.

A. 0
B. (b . c)(e . f) [ d + a ]c) (b . c)(e . f) [ d – a ]d) (b .
C. X (e . f)d ] X [ a – d ].‘X’ represents cross product while ’.‘ represents dot product. Vectors a & d are perpendicular.a) 0b) (b . c)(e . f) [ d + a ]c) (b . c)(e . f) [ d – a ]
D. (b . c)(e . f) [ d X a ]
Answer» C. X (e . f)d ] X [ a – d ].‘X’ represents cross product while ’.‘ represents dot product. Vectors a & d are perpendicular.a) 0b) (b . c)(e . f) [ d + a ]c) (b . c)(e . f) [ d – a ]
