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) + 2 vec(B)

1.	If (vec(A) + vec(B)) is perpendicular to vec(B) and (vec(A) + 2 vec(B)) is perpendicular to vec(A), then
Answer» `A = sqrt2B` A = 2B 2A = B A = B Answer :A
