Solved 1 A Evaluate The Cross Product Of The Vectors Chegg Physics questions and answers; question 1 b z 2. evaluate the cross product a x b of the two vectors above. they are separated by an angle of 40.0' and have magnitudes given by vector a: 8.00 vector b: 8.00 (41.1 out of the screen) (49.0, out of the screen) (41.1. into the screen) (49.0, into the screen). Using equation 2.9 to find the cross product of two vectors is straightforward, and it presents the cross product in the useful component form. the formula, however, is complicated and difficult to remember. fortunately, we have an alternative. we can calculate the cross product of two vectors using determinant notation. The cross product (purple) is always perpendicular to both vectors, and has magnitude zero when the vectors are parallel and maximum magnitude ‖ ⇀ a‖‖ ⇀ b‖ when they are perpendicular. (public domain; lucasvb). example 12.4.1: finding a cross product. let ⇀ p = − 1, 2, 5 and ⇀ q = 4, 0, − 3 (figure 12.4.1). The first step is to redraw the vectors →a and →b so that the tails are touching. then draw an arc starting from the vector →a and finishing on the vector →b . curl your right fingers the same way as the arc. your right thumb points in the direction of the vector product →a × →b (figure 3.28). figure 3.28: right hand rule.
