In unit-vector notation, what is the torque about the origin on a jar of jalapeno peppers located

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?
(a) Force F2 = (3.0N) i – (4.0N) j + (5.0) k,
(b) Force F2 = (-3.0N) i – (4.0N) j – (5.0N) k, and
(c) The vector sum of F1 and F2?
(d) Repeat part (c) for the torque about the point with coordinates (3.0 m,
2.0 m, 4.0 m)
