Is the vector `A = (hati) - (hatj) + 2 hatk` parallel to a vector `B = 3hat i - 3hat j + 6hat k`.

A

No

B

Yes

C

May be

D

Incomplete Info

Text Solution

Verified by Experts

The correct Answer is:
B
A vector A is parallel to an another vector B if it can be Written as
`A=mB`
`Here, A=(hati-hatj+2hatk)=(1)/(3)(3hati-3hatj+6hatk)`
`"(":'B=3hati-3hatj+6hatk)`
`:. A=(1)/(3)B`
this implies that A is parallel to B and magnitude of A is 1/3 times the magniude of B.
