Two vector A and B have equal magnitudes. Then the vector `A+B` is perpendicular to

Two vector vec(A) and vec(B) have equal magnitudes. Then the vector vec(A) + vec(B) is perpendicular :

Two vectors A and B lie in X-Y plane. The vector B is perpendicular to vector A. If A=hati+hatj , then B may be -

Two vectors vec A and vec B have equal magnitudes.If magnitude of (vec A+vec B) is equal to n xx of the magnitude of (vec A-vec B) then the angle between vec A and vec B is :

Two vectors vec A and vec B have equal magnitudes. If magnitude of vec A-vec B is equal to (n) times the magnitude of vec A-vec B , then angle between vec A and vec B is ?

Two vectors vec(A) and vec(B) have equal magnitudes . If magnitude of vec(A) + vec(B) is equal to n times the magnitude of vec(A) - vec(B) , then the angle between vec(A) and vec(B) is

Two vector vec(A)andvec(B) have equal magnitudes. If magnitude of vec(A)+vec(B) is equal to n time the magnitude of vec(A)-vec(B) , then angle to between vec(A) and vec(B) is

The vector product of two vectors will have maximum magnitude when theta is equal to

Resultant of two vectors one having magnitude twice of other is perpendicular to the smaller vector then find the angle ( " in"^@) between the vectors ?
