If `bar a, barb, barc` are three mutually perpendicular vectors of equal magnitude, then the angle made by `bar a+barb+barc` with each of `bar a, barb, barc` is

If bara,barb,barc are mutually prependicular vectors having megnitudes 1,2,3 respectively, then [bara+barb+bar(c) bar(b)-bara" "barc]=

Let bara, barb and barc be mutually orthogonal vectors of equal magnitudes. Prove that the vector bara+barb+barc is equally inclined to each of bara, barb and barc , the angle of inclination being cos^(-1)" 1/sqrt3

If bara,barb,barc are mutually prependicular vectors having megnitudes 1,2,3 respectively, then [bara+barb+bar(c)" "bar(b)-bara" "barc]=

If bara , barb , barc are three vectors,then [bara barb barc] is not equal to

If bara,barb,barc are three vectors, then [bara,barb,barc] is not equal to

If bara,barb,barc are three vectors, then [bara, barb, barc] is not equal to

If bara. barb = barb. barc = barc . bara = 0 then [bara barb barc] =

If bara, barb, barc are unit vectors satisfying bara-sqrt(3)barb+barc=bar0 , then the angle between the vectors bara and barc is :

bara,barb,barc are mutually perpendicular unit vectors and bard is a unit vector equally inclined to each of bara,barb and barc " at an angle of " 60^(@). " Find the value of " abs(bara+barb+barc+bard)^(2) .
