Ina two-dimensional tug-of-war, Alex, Betty, and Charles pull horizontally on an automobile tire at the angles shown in the picture. The tire remains stationary in spite of the three pulls. Alex pulls with force ÉA of magnitude 217 N, and Charles pulls with force É cof magnitude 180 N. Note that the direction of É cis not given. What is the magnitude of Betty's force É B if Charles pulls in (a) the direction drawn in the picture or (b) the other possible direction for equilibrium? Alex Charles
