value of a unit vector in the direction ...

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

A

`hati`

B

`hat j`

C

`(hat i+hat j)/(13)`

D

`(5hat i-12hat j)/(13)`

Verified by Experts

The correct Answer is:

d

`hatn=(barA)/(|barA|)=(5hati -12 hatj)/sqrt(5^(2)+12^(2))=(5hati -12hatj)/(13)`
