25. We use the notation G ′ r to indicate the vector pointing from the axis of rotation directly to the position of the particle. If we write G ′ = ′ + ′ + ′ rx y z ### i j k, then (using Eq. 3-30) we find G G ′ × r F is equal to ′ − ′ + ′ − ′ + ′ − ′ yF zF zF xF yF zy xz y x di b g ## # ijk . (a) Here, G G ′ = r r . Dropping the primes in the above expression, we set (with SI units understood) x = 0, y = 0.5, z = –2.0, F x = 2.0, F y = 0 and
