Given : `vecA =2 hati + 3hatj+hatk and vecB = 6 hati + 9hatj+3hatk ` which of the following statements is correct ?

A

`vec A and vecB` are equal vectors

B

`vec A and vecB` are parallel vectors

C

`vec A and vecB` are perpendicular vectors

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Given : `vecA = 2 hati + 3 hat j + hatk and vecB = 6 hati + 9 hatj + 3hatk`
`:. vecB = 3 (2 hati + 3hatj + hatk), " As" vecB = 3vecA :. vecB ||vecA`
