Question

find the unit vectorof Avector =5icap -12jcap

Answer 1

To find a unit vector with same direction as given vector, we divide by the magnitude of the vector.

IvI  =√(5)²+(-12)²

     =13

Therefore divide the given vector by its magnitude 13.

So, the unit vector is =(5/13) i^ - (12/13) j^

Answer 2

your answer is ---


Given ,

vector A = 5i^ - 12j^

it's magnitude is

|A| = √5^2+(-12)^2

= √25+144 = √169

= 13


Now , we know that


vectorA = |A| A^

=> A^ = vectorA/|A|

=> A^ = (5i^ - 12j^)/13
