List of top Mathematics Questions on Product of Two Vectors asked in TS EAMCET

Let \[ \vec a=i+2j+2k,\quad \vec b=2i-j+2k,\quad \vec c=2i+j+2k \] If \(\vec d\times \vec a=\vec b\times \vec a\) and \(\vec d\cdot \vec c=8\), then for \(\vec r=2i+2j+k\), find \(\vec d\cdot \vec r\)

Let \(\vec a=i+j+k\), \(\vec b=i-j+k\). If \(\vec c \perp \vec a\), \(\vec d \parallel \vec a\), and \(\vec b=\vec c+\vec d\), then \((\vec c\times \vec d)^2=\)
