" 6.If "vec a,vec b" and "vec c" are mutually perpendicular,show that "[vec a*(vec b timesvec c)]=a^(2)b^(2)c^(2)

If vec a,vec b and vec c are mutually perpendicular, show that [vec a*(vec b xxvec c)]^(2)=a^(2)b^(2)c^(2)

If vec a, vec b, vec c are mutually perpendicular unit vectors then |vec a + vec b + vec c| =

If vec a,vec b,vec c are mutually perpendicular unit vectors,find |2vec a+vec b+vec c|

If vec a , vec b , vec c are mutually perpendicular unit vectors, find |2 vec a+ vec b+ vec c|dot

If vec a , vec b , vec c are mutually perpendicular unit vectors, find |2 vec a+ vec b+ vec c|dot

If vec a and vec b are mutually perpendicular unit vectors,write the value of |vec a+vec b+vec c|

If vec a and vec b and vec c are mutually perpendicular unit vectors,write the value of |vec a+vec b+vec c|

If vec a,vec b,vec c are three mutually perpendicular unit vectors,then prove that |vec a+vec b+vec c|=sqrt(3)

Let vec a,vec b and vec c be pairwise mutually perpendicular vectors,such that |vec a|=1,|vec b|=2,|vec c|=2. Then find the length of vec a+vec b+vec c
