The angle between A+B and AxB is |
|
Answer» Given ;two vectors A and B.A and B are two vectors.So,their sum A+Blies in the same PLANE where A and B lie (SINCE they are non-parallel so they define a plane and CROSS product between them is not zero.)A×B=|A| |B| sin×alpha×n,where alpha is the angle between A and B and n is the unit vector perpendicular to the plane containing A and B So,the angle between (A+B) and (A×B) is 90°.Mathematically,=|A+B||A×B|cos alpha=(A+B).(A×B)=A.(A×B)+B.(A×B)=B.(A×A)+A.(B+B)=0+0Answer is 90°(DEGREE)✔*❤THANKS❤* |
