The force F $=$ i$+3$j$+2$k acts at the point $(1,1,1).($a$)$ Find the torque of the force about the point $(2,1,5).$ Careful! The vector r goes from $(2,1,5)$ to $(1,1,1).($b$)$ Find the torque of the force about the line r $=2$i$$j$+5$k$+($i$$j$+2$k$)$t$.$Note that the line goes through the point $(2,1,5)$
