Unit vector parallel to the resultant of vector `8hati` and `8hatj` will be

A

`(24hati+5hatj)//13`

B

`(12hati+5hatj)//13`

C

`(6hati+5hatj)//13`

D

None of therse

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Resultant of two given vector will be
`sqrt((8)^(2)+(8)^(2))=8sqrt(2)`
`therefore `Uniot vector parallel to the given vecoterwill be
`(hati+hatj)/(sqrt(2))`
