Question: Two rectangular plates are hinged together and held by a wire extending from corner C to corner B . The tension in wire BC is

Two rectangular plates are hinged together and held by a wire extending from corner C to corner B . The tension in wire BC is 485 N . You want to examine the rotational effects of the tension force in the wire applied at corner C of the plate about the origin of the coordinate system, 0.
You decide to choose a position vector that originates at the origin and ends at point C. Based on that decision, which moment vector below would be the correct result of calculating the moment of the force on corner C of the plate by wire BC about the origin of the coordinate system, 0.
Multiple Choice
vec(Mo)=(316.61N-m)hat(i)-(281.54N-m)hat(j)+(237.46N-m)hat(k)
vec(Mo)=(653.3N*m)hat(i)-(290.4N*m)hat(j)+(925.6N-m)hat(k)
Mo2=(-316.61N-m)hat(i)+(281.54N-m)hat(j)-(237.46N*m)hat(k)
vec(Mo)=(-653.3N*m)hat(i)+(290.4N*m)hat(j)-(925.6N-m)hat(k)
