Bob and Ray push on a door from opposite sides. They both push perpendicular to the door. Bob pushes 0.63 m from the door hinge with a force of 89 N. Ray pushes 0.57 m from the door hinge with a force of 98 N, in a manner that tends to turn the door in a clockwise direction. What is the net torque on the door?
I put 2.46n.m and got this wrong can someone please help me!
τ = 89•0.63 -98•0.57 =
=56.7-55.86 = 0.84 N•m (anticlockwise)
