A worker opens a 1.10 m wide door by pushing on it with a force of 53.5 N directed perpendicular to its surface.

(a) What magnitude torque (in N · m) does she apply about an axis through the hinges if the force is applied at the center of the door? N · m

(b) What magnitude torque (in N · m) does she apply at the edge farthest from the hinges? N · m
