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

`- 2hati + 6 hatj + 4 hatk`

B

`- 2hati + 3 hatj + 3 hatk`

C

`- 2hati + 3 hatj + 5 hatk`

D

` 2hati - 3 hatj - 3 hatk`

Text Solution

Verified by Experts

The correct Answer is:
C
`vecr_A=0hati+3hatj-hatk,vecrB=-2hati+6hatj=4hatk`

Displacement vector from `vecr=vecr_B-vecr_A=(-2hati+6hatj+4hatk)-(0hati+3hatj-hatk)=-2hati+3hatj+5hatk`
