1.	vec(A) and vec(B) are two vectors. Then correct options are
Answer» If `vec(A) + vec(B)`magnitude is equal to magnitude of `vec(A) - vec(B)` magnitude angle between `vec(A) and vec(B)` is `90^(@)` If angle between `vec(A) + vec(B) and vec(A) - vec(B) " is " 60^(@)` their resultant is `SQRT(3A^(2) + B^(2))` If `vec(A) + vec(B) and vec(A) - vec(B)` vectors are PERPENDICULAR `vec(A) - vec(B)` is a null vector `(vec(A) + vec(B)).(vec(A)- vec(B)) = 0` if `vec(A) and vec(B)` have equal magnitude Answer :A::B
