If `vec(A)=2hat(i)+3hat(j)-hat(k)` and `vec(B)=-hat(i)+3hat(j)+4hat(k)`, then find the projection of `vec(A)` on `vec(B)`.

If vec(a) = 2hat(i) + hat(j) + 2hat(k), vec(b) = 5hat(i) - 3hat(j) + hat(k) , then projection of vec(a) on vec(b) is

If vec(a) = 2 hat(i) + 3hat(j) + 6hat(k) and vec(b) = 3hat(i) + 4hat(j) , then ("projection of " vec(a) " on " vec(b))/("projection of" vec(b) " on " vec(a))

If vec(a) = hat(i) + hat(j) + 2 hat(k) and vec(b) = 3 hat(i) + 2 hat(j) - hat(k) , find the value of (vec(a) + 3 vec(b)) . ( 2 vec(a) - vec(b)) .

If vec a = 7 hat i +hat j - 4 hat k and vec b=2 hat i+6 hat j +3 hat k , then find the projection of vec a on vec b .

If vec(a)=2hat(i)-5hat(j)+3hat(k) " and " vec(b)=hat(i)-2hat(j)-4hat(k) , find the value of abs(3vec(a)+2vec(b)).

If vec(a)=3hat(i)-2hat(j)+hat(k), vec(b)=2hat(i)-4 hat(j)-3 hat(k) , find |vec(a)-2 vec(b)| .
