magnitude of vector and triangle law

The resultant of the vectors A and B is perpendicular to the vector A and its magnitude is equal to half the magnitude of vector B. The angle between vecA" and "vecB is :-

The resultant of two vectors A and B is perpendicular to the vector A and its magnitude is equal to half the magnitude of vector B. The angle between A and B is -

The magnitude of a vector cannot be :

The sum of the magnitudes of two vectors P and Q is 18 and the magnitude of their resultant is 12. If the resultant is perpendicular to one of the vectors, then the magnitudes of the two vectors are

The magnitude of a vector cannot be

If the magnitudes of two vectors are 2 and 3 and the magnitude of their scalar product is 3 sqrt 2 , then find the angle between the vectors.

If the magnitude of two vectors are 4 and 6 and the magnitude of their scalar product is 12sqrt2 what is the angle between the vectors?

If the magnitudes of two vectors are 3 and 4 and magnitude of their scalar product is 6 what is the angle between the vectors ?

If the magnitudes of two vectors are 2 and 3 and magnitude of their scalar product is 2sqrt3 what is the angle between the vectors ?
