Question

Q.6) Find the magnitude of A=3i+2j-6k and the unit vector is in direction A plz help for answer (don't spam)​

Answer 1

Answer:

please mark me as brainliest answer

Explanation:

magnitude = 7

unit vector = 3/7 i + 2/7 j - 6/7 k

Explanation:

magnitude = sqrt(3^2 + 2^2 + 6^2) =

sqrt(9+4+36)

= sqrt (49) = 7

unit vector = vector / magnitude = 3/7 i +

2/7j - 6/7 k
