lf the magnitudes of →A,→B,→C are 12,5,13 units respectively and →A+→B=→C, then the angle between →A, →B is:
The magnitudes of vectors →A,→Band→C are 3, 4 and 5 units respectively. If →A+→B=→C, the angle between →A and →B is
The magnitude of vector →A,→B and →C are respectively 12, 5 and 13 units and →A+→B=→C then the angle between →A and →B is
