Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

let U be orthogonal complement of V. 1) Zero subspace is subset of U, since U is a vector space. 2) conversely, let x € U. Then, x belongs to V such that = 0, for all y in V, that is x is orthogonal to each vector of V. But we know that zero vector is the only such vector. So, x = 0. hence, this enforces U is contained in {0}. From 1) &2), U = zero space
