Show that the area of the triangle contained between the vector overset rarr(r ) and overset rarr(b) is one half of the magnitude of overset rarr(a) xx overset rarr(b)

The angle between the vectors i-j+k and -i+j+2k is

If the angle between two vectors of equal magnitude P is "theta" ,the magnitude of the difference of the vectors is

If the angle between two vectors of equal magnitude "P" is theta the magnitude of the difference of the vectors is

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 -

Two vectors of equal magnitude P are inclined at some angle such that the difference in magitude of resultant and magnitude of either of the vectors is 0.732 times either of the magnitude of vectors. If the angle between them is increased by half of its initial value then find the magnitude of difference of the vectors
