Given : vecA =2 hati + 3hatj+hatk andvecB = 6 hati + 9hatj+3hatkwhich

1.	Given : vecA =2 hati + 3hatj+hatk andvecB = 6 hati + 9hatj+3hatkwhich of the following statements is correct ?
Answer» `vec A and vecB` are EQUAL vectors `vec A and vecB` are parallelvectors `vec A and vecB` are perpendicularvectors None of these Solution :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`
