QUESTION 5 Two vectors have the following magnitude, A = 7.3 m and B = 11.1 m. Their vector product is: AxB = -3.4 m i+ 6.8 m k. What is the angle (in degrees) between the vectors A and B? Hint: Use |AxB| = AB sin(0) Note: Bold face letters represents a vector.
A definition of the cross product is the following: x B = |Ã||B| sin 0 where 0 is the angle between the vectors. We would read this equation as A crossed B is equal to the magnitude of vector A times the magnitude of vector B times sine of the angle between vector A and B. Unlike the dot product, the cross product looks at the product of perpendicular components, and the consequence of this is the resulting vector of the cross product is perpendicular to each of the two vectors. Suppose |A| = 3 and |B| = 4. If the angle between A and B is 30°, then what is the magnitude of A × B ? 12 0.5 Insufficient information
