Let ` vec aa n d vec b` be unit vectors that are perpendicular to each other. Then `[ vec a+( vec axx vec b) vec b+( vec axx vec b) vec axx vec b]` will always be equal to `1` b. `0` c. `-1` d. none of these

Let vec a and vec b are two unit vectors that are mutually perpendicular.A unit vector that is equally inclined to vec a.vec b and vec a xxvec b is :

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

The vector component of vec b perpendicular to vec a is ( vec bdot vec c) vec a b. ( vec axx( vec bxx vec a))/(| vec a|^2) c. vec axx( vec bxx vec a) d. none of these

For any three vectors adotb\ a n d\ c write the value of vec axx( vec b+ vec c)+ vec bxx( vec c+ vec a)+ vec cxx( vec a+ vec b)dot

If vec a, vec b, vec c are three mutually perpendicular vectors such that | vec a | = | vec b | = | vec c | then (vec a + vec b + vec c) * vec a =

vec aa n d vec b are two unit vectors that are mutually perpendicular. A unit vector that is equally inclined to vec a , vec ba n d vec axx vec b is a.1/(sqrt(2))( vec a+ vec b+ vec axx vec b) b. 1/2( vec axx vec b+ vec a+ vec b) c. 1/(sqrt(3))( vec a+ vec b+ vec axx vec b) d. 1/3( vec a+ vec b+ vec axx vec b)

If vec a,vec b, and vec c are unit vectors such that vec a+vec b+vec c=0, then find the value of vec a*vec b+vec b*vec c+vec c*vec a

For any two vectors vec a\ a n d\ vec b , fin d\ ( vec axx vec b). vecbdot

vec b and vec c are unit vectors.Then for any arbitrary vector vec a,(((vec a xxvec b)+(vec a xxvec c))xx(vec b xxvec c))vec b-vec c is always equal to a.|vec a| b.(1)/(2)|vec a| c.(1)/(3)|vec a| d.none of these
