Question

. If a vector A=2î +2 +3k, and B=3i +61 +nk,
are perpendicular to each other then the
value of 'n' is
1) 4 2) 12 3) 6 4) -6​

Answer 1

Answer:since it is perpendicular the dot product=-1

Step-by-step explanation:

Answer 2

Answer:

A. B=0

If they are perpendicular to each other

A. B=a1a2 +b1b2 +c1c2

2×3+2×6+3×n=0

6+12+3n=0

18+3n=0

3n=-18

n=-18/3=-6

n=-6
