If ` vec a , vec b ,a n d vec c` are there mutually perpendicular unit vectors and ` vec d` is a unit vector which makes equal angles with ` vec a , vec b ,a n d vec c` , the find the value off `| vec a+ vec b+ vec c+ vec d|^2dot`

If vec a,vec b, and vec c are there mutually perpendicular unit vectors and vec d is a unit vector which makes equal angles with vec a,vec b, and vec c, the find the value off |vec a+vec b+vec c+vec d|^(2)

if vec a,vec b and vec c are there mutually perpendicular unit vectors and vec a ia a unit vector make equal angles which vec a,vec b and vec c then find the value of |vec a+vec b+vec c+vec d|^(2)

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

vec a,vec b,vec c are mutually perpendicular unit vectors and vec d is a unit vector equally inclined to each other of vec a,vec b and vec c at an angle of 60^(@) then |vec a+vec b+vec c+vec d|^(2)=

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

Statement 1: vec a , vec b ,a n d vec c are three mutually perpendicular unit vectors and vec d is a vector such that vec a , vec b , vec ca n d vec d are non-coplanar. If [ vec d vec b vec c]=[ vec d vec a vec b]=[ vec d vec c vec a]=1,t h e n vec d= vec a+ vec b+ vec c Statement 2: [ vec d vec b vec c]=[ vec d vec a vec b]=[ vec d vec c vec a] =>vec d is equally inclined to veca,vecb,vecc.

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

If vec a\ a n d\ vec b are unit vectors then write the value of | vec axx vec b|^2+( vec adot vec b)^2dot

If vec a,vec b,vec c are three mutually perpendicular vectors of equal magniltgude,prove that vec a+vec b+vec c is equally inclined with vectors vec a,vec b, and vec r also find the angle.
