Question

the value of a unit vector in the direction of vector A=5i^-12j^ is

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^
