Questions
If , then which of the following statements is wrong
a
C→⊥A→
b
C→⊥B→
c
C→⊥(A→+B→)
d
C→⊥(A→×B→)
detailed solution
Correct option is D
From the property of vector product, we notice that C→ must be perpendicular to the plane formed by vector A→ and B→. Thus C→ is perpendicular to both A→ and B→ and A→+B→ vector also must lie in the plane formed by vector A→ and B→ . Thus C→ must be perpendicular to A→+B→ but the cross product A→×B→ gives a vector C→ which cannot be perpendicular to itself. Thus the last statement is wrong.Talk to our academic expert!
