Explanation:
A and B are two vectors. So, their sum A+B lies in the same plane where A and B lie
A×B=∣A∣∣B∣sinαn , where α is the angle between A and B and n is the unit vector perpendicular to the plane containing A and B
The angle between (A+B) and (A×B) is 90 degrees.
∣A+B∣∣A×B∣cosα=(A+B). (A×B)
=A.(A×B)+B.(A×B)
=B.(A×A)+A.(B×B)
=0+0
