A meterstick is oriented in space parallel to the unit vector given by r̂ = 2/15 î + 10/15 ĵ + 11/15 k̂ , with one of its end located at the origin of a Cartesian coordinate system. Considering the origin as the pivot point, calculate the torque due to a 12.5-N force, oriented parallel to the unit vector given by r̂ = 3/13 î - 4/13 ĵ + 12/13 k̂ , acting on the meterstick at the 0.75-m mark. Express your answer in the î -  ĵ - k̂ notation. (Hint: î x ĵ = k̂,  ĵ x k̂ = î,  k̂ x î = ĵ )
