Prove that the vectors a=2i-3j+k and b=i+j+k are mutually perpendicula

1.	Prove that the vectors a=2i-3j+k and b=i+j+k are mutually perpendicular
Answer» ANSWER: the condition of PERPENDICULAR vector are (a.b)=0 a.b= (2i-3j+k).(i+j+k)= 2-3+1=0 hence the condition SATISFIED so both vectors are mutually perpendicular. (PROVED)

Prove that the vectors a=2i-3j+k and b=i+j+k are mutually perpendicular

Answer»

ANSWER:

the condition of PERPENDICULAR vector are (a.b)=0

a.b= (2i-3j+k).(i+j+k)= 2-3+1=0

hence the condition SATISFIED so both vectors are mutually perpendicular. (PROVED)
