The (x,y,z) co -ordinates of two points ...

The (x,y,z) co -ordinates of two points A and B are give respectively as (0,3,- 1) and (-2,6,4) The displacement vector from A to B is given by

A

`-2 hati+6hatj+4hatk`

B

`-2hati+3hatj+3hatk`

C

`-2hati+3hatj+5hatk`

D

`2hati-3hatj-5hatk`

Text Solution

Verified by Experts

The correct Answer is:
C
`s=r_B - r_A`
`=(-2hati +6hatj + 4hatk) - (3hatj-hatk)`
`=- 2hati + 3hatj + 5hatk.`
