(I) If vector $\stackrel{\to }{A}$ points along the negative x axis and vector $\stackrel{\to }{B}$ along the positive z axis, what is the direction of (a) $\stackrel{\to }{A}\times \stackrel{\to }{B}$ and (b) $\stackrel{\to }{B}\times \stackrel{\to }{A}$? (с) What is the magnitude of $\stackrel{\to }{A}\times \stackrel{\to }{B}$ and $\stackrel{\to }{B}\times \stackrel{\to }{A}$?
