Two forces equalin magnitude and opposite in direction,acting on an object at two different points,from what is called a couple. Two anti parallel forces w ith equalmagnitudes F1 = F2 = 8.00 N are applied to a rod as shown in f igure. What should the distance 1between the forces be if they are to provide a net torque of 6.40 N. m about the left end of the rod?
