Question

the angle between vector A=
2j-3j+k and B=i+j+k is​

Answer 1

Answer:

Answer:Given:-

Answer:Given:-A = 2i - 3j + k

- 3j + k B = i + j + k

- 3j + k B = i + j + k|A| = √ (2)^2 + (3)^2 + (1)^2

= √ 4 + 9+ 1 = √14

|B| = √ (1)^2 + (1)^2 +(1)^2

= √3

To find angle between vector we can use formula

To find angle between vector we can use formula

Coso = {A (vector) . B( vector ) }/ |A||B|

= { ( 2i - 3j + k ) . ( i + j + k ) / √14* √3

= { 2 - 3 +1 } / √14*√3

= 0

O = 90°
