If `veca,vecb,vecc` are mutually perpendicular vectors of equal magnitude show that `veca+vecb+vecc` is equally inclined to `veca, vecb and vecc`

if veca,vecb and vecc are mutally perpendicular vectors of equal magnitudes, then find the angle between vectors and veca+ vecb+vecc .

If veca,vecb,vecc are three mutually perpendicular vectors, then the vector which is equally inclined to these vectors is (A) veca+vecb+vecc (B) veca/|veca|+vecb/|vecb|+vec/|vecc| (C) veca/|veca|^2+vecb/|vecb|^2+vecc/|vecc|^2 (D) |veca|veca-|vecb|vecb+|vecc|vecc

If veca, vecb, vecc are mutually perpendicular vectors having magnitude 1,2,3 respectively, then [vec(a)+vecb+vecc, vecb-veca, vecc] =

If veca,vecb and vecc are three mutually perpendicular unit vectors and vecd is a unit vector which makes equal angal with veca,vecb and vecc , then find the value of |veca+vecb+vecc+vecd|^(2) .

If veca,vecb and vecc are three mutually perpendicular unit vectors and vecd is a unit vector which makes equal angal with veca,vecb and vecc , then find the value of |veca+vecb+vecc+vecd|^(2) .

If veca, vecb, vecc are three non-coplanar mutually perpendicular unit vectors, then [(veca, vecb, vecc)] is

Let veca vecb and vecc be pairwise mutually perpendicular vectors, such that |veca|=1, |vecb|=2, |vecc| = 2 , the find the length of veca +vecb + vecc .

Let veca vecb and vecc be pairwise mutually perpendicular vectors, such that |veca|=1, |vecb|=2, |vecc| = 2 , the find the length of veca +vecb + vecc .

Statement 1: veca, vecb and vecc arwe three mutually perpendicular unit vectors and vecd is a vector such that veca, vecb, vecc and vecd are non- coplanar. If [vecd vecb vecc] = [vecdvecavecb] = [vecdvecc veca] = 1, " then " vecd= veca+vecb+vecc Statement 2: [vecd vecb vecc] = [vecd veca vecb] = [vecdveccveca] Rightarrow vecd is equally inclined to veca, vecb and vecc .

If veca, vecb, vecc are any three non coplanar vectors, then [(veca+vecb+vecc, veca-vecc, veca-vecb)] is equal to
