A particle is located at the vector position r = (1.3 m)i+ (4.1 m)j and the force acting on it is F= (2.6 N)i+ (3.8 N) j . What is the magnitude of the torque about the origin? Answer in units of N m So I have I J K 1.3 4.1 0 2.6 3.8 0 I took i(0-0)+j(0-0)+k(4.94-10.66) = -5.72 my answer was wrong....what am I doing wrong?
