यदि `vecr_(1) = 3hati -2hatj + hatk, vecr_(2) = 2hati - 4hatj - 3hatk` तथा `vecr_(3) = -hati + 2hatj + 2hatk, 2vecr_(1) - 3vecr_(2) -5vecr_(3)` का मापांक निकालें|

Answer» `2vecr_(1) - 3vecr_(2) - 5vecr_(3) = 5hati - 2hatj + hatk`
`therefore |2vecr_(1)-3vecr_(2) - 5vecr_(3)| = sqrt(5^(2) + (-2)^(2) + 1^(2))=sqrt(30)`
