If a vector is subtracted by the same vector, then we get

Vectors are

If |alpha vector + beta vector | = | alpha vector - beta vector|

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

Assertion - Vector addition of two vector is always greater then their vector subtraction. Reason At theta =90^(@) , addition and subtraction of two vector are equal .

The algebraic sum of two co - initial vectors is 16 units. Their vector sum is 8 units and the resultant of the vectors are perpendicular to the smaller vector. Then magnitudes of the two vectors are -

If hatn is a unit vector in the direction of the vector vecA , then:-

If hatn is a unit vector in the direction of the vector vecA , them :

If hatn is a unit vector in the direction of the vector vecA , them :

If the vector -hati +hatj-hatk bisects the angle between the vector vecc and the vector 3hati +4hatj, then the vector along vecc is

If a vector vec(A) is parallel to another vector vec(B) then the resultant of the vector vec(A)xxvec(B) will be equal to
