Show that if two vectors are equal in magnitude, their vector sum and difference are at right angles.

The resultant vecR of two vectors has magnitude equal to one of the vectors and is at right angle to it . Find the value of the other vector.

If the magnitude of sum of two vectors is equal to the magnitude of difference to two vectors, the angle between these vector 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

If resultant of two vectors of equal magnitude is equal to the magnitude of either vector, then what is the angle between these vectors?

If the magnitude of sum of two vectors is equal to the magnitude of difference of the two vector, the angle between these Vector is

If the magnitude of sum of two vectors is equal to the magnitude of difference of the two vector, the angle between these Vector is
