Let, veca = hati+2hatj` and `vecb = 2hati+hatj`. If `|veca| = |vecb|`. Are the vectors `veca&vecb` equal?

Explanation

Given , `veca = hati+2hatj` and `vecb = 2hati+hatj`. Here `|veca| = sqrt(1^2+2^2) = sqrt5` and `|vecb| = sqrt(2^2+1^2) = sqrt5`.
Therefore, `|veca| = |vecb|. But vectors are not equal since the corresponding components are distinct i.e, direction are different.
