if `veca, vecb and vecc` are there mutually perpendicular unit vectors and `veca` ia a unit vector make equal angles which `veca, vecb and vecc` then find the value of ` |veca+ vecb + vecc + vecd|^2`

If veca, vecb, vecc are three mutually perpendicular unit vectors then |veca+vecb+vecc| is

If veca,vecb,vecc are three mutually perpendicular unit vectors, then prove that abs(veca+vecb+vecc)=sqrt3

Statement 1: veca, vecb and vecc are 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 . Option A: Both the statements are true and statement 2 is the correct explanation for statement 1. Option B: Both statements are true but statement 2 is not the correct explanation for statement 1. Option C: Statement 1 is true and Statement 2 is false Option D: Statement 1 is false and Statement 2 is true.

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