    9. Which of the following statements are true and which are false? Justify your answer with
    a short proof or a counterexample. (10)
    I) R2 has infinitely many non-zero, proper vector subspaces.
    ii) If T : V →W is a one-one linear transformation between two finite dimensional
    vector spacesV and W then T is invertible.
    iii) If Ak = 0 for a square matrix A, then all the eigenvalues of A are zero.
    iv) Every unitary operator is invertible.
    v) Every system of homogeneous linear equations has a non-zero solution.
