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

If vec(a) = 2hat(i) + hat(j) - hat(k) and vec(b) = hat(i) - hat(k) , then projection of vec(a) on vec(b) will be :

If vec(a) = 2hat(i) + hat(j) - hat(k) and vec(b) = hat(i) - hat(k) , then projection of vec(a) on vec(b) will be :

If vec(a) = 2hat(i) + 3hat(j) - 6hat(k) and vec(b) = 12 hat(j) + 5 hat(k) . then (projection of vec(a) on vec(b)//("projection of b on a") )

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)=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) .
