Q.2:What is meant by?

1- The dot product of two vectors A and B = 75.2.

 2- The vector product of two vectors A and B = 43.6 n.

  1. – The dot product of two vectors A and B =75.2.

It's mean that the product of the magnitudes of ( A ) and ( B ) and the cosine of the angle between them = 75.2 or  AB cos ø =75.2

2– The cross product of two vectors  → and B  = 43.6 n . It's mean that the product of the magnitudes of (A→) and (  B →) and the sine of the angle between them and the unit vector directed in a direction perpendicular to the plan of both vectors = 43.6 n→ ,or A B sine Øn→ = 43.6 n →
