Question

In unit-vector notation, what is the torque about the origin on a jar of jalapeno peppers located at coordinates (3.0 m, -2.0 m, 4.0 m) due to force  F→1 = (4.7 N) î - (2.6 N) ĵ + (7.4 N) k̂ ((a), (b) and (c) for î , ĵ and k̂ components respectively), force  F→2 = (-4.7 N) î - (2.6 N) ĵ - (7.4 N) k̂ ((d), (e) and (f) for î , ĵ and k̂ components respectively), and the vector sum of F→1 and F→2 ((g), (h) and (i) for î , ĵ and k̂ components respectively)? Repeat previous part for the torque about the point with coordinates (3.0 m, 2.0 m, 4.0 m) ((j), (k) and (l) for î , ĵ and k̂ components respectively).
