Let \(\vec{a}=\hat{i}+\hat{j}+\hat{k}, \vec{b}\) and \(\vec{c}=\hat{j}-\hat{k}\) be three vectors such that \(\vec{a} \times \vec{b}=\vec{c}\) and \(\vec{a} \cdot \vec{b}=1\). If the length of projection vector of the vector \(\vec{b}\) on the vector \(\vec{a} \times \vec{c}\) is \(\ell\), then the value of \(3 \ell^2\) is equal to.____________ 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
