" If "vec A" is perpendicular to "vec B," then "

If vec A,vec B&vec A+vec B are three non-zero vector. Such that vec A+vec B is perpendicular to vec B then which of one is correct:

vec r xxvec a=vec b xxvec a;vec r xxvec b=vec a xxvec b;vec a!=vec 0;vec b!=vec 0;vec a!=lambdavec b, and vec a is not perpendicular to vec b, then find vec r in terms of vec a and vec b

vec rxx vec a= vec bxx vec a ; vec rxx vec b= vec axx vec b ; vec a!= vec0; vec b!= vec0; vec a!=lambda vec b ,a n d vec a is not perpendicular to vec b , then find vec r in terms of vec aa n d vec bdot

vec r xxvec a = vec b xxvec a, vec r xxvec b = vec a xxvec b, vec a! = 0, vec b! = 0, vec b! = lambdavec a, vec a is not perpendicular to vec b then vec r is

If vec(A) + vec(B) = vec(R ) and 2 vec(A) + vec(B) is perpendicular to vec(B) then

If (vec(A) + vec(B)) is perpendicular to vec(B) and (vec(A) + 2 vec(B)) is perpendicular to vec(A) , then

If vec a+vec b is perpendicular to vec b and vec a+vec 2b is perpendicular to vec a then

If vec(A),vec(B) & vec(A)+vec(B) are three non - zero vector. Such that vec(A)+vec(B) is perpendicular to vec(B) then which of one is correct :
