[-/2 Points] DETAILS OSUNIPHYS1 2.4. WA. 059 . MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER In the diagram below, [A| = 3.02, [B| = 4.06, 8, = 20.0, and 02 = 40.8. The two vectors lie in the x-y plane. We use the standard rectangular coordinate system, with +x to the right, +y vertically up, and +z coming out toward you. (a) What is the magnitude of the cross product of the two vectors? A x BI = b) What is the direction of the cross product of the two vectors? O +x O - > O +y O - y O +z O -z O no direction Additional Materials Reading 6. [-/1 Points] DETAILS OSUNIPHYS1 2.4. WA.061.
