In a 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 F A of magnitude 219 N, and Charles pulls with force É c of magnitude 187 N. Note that the direction of F c is not given. What is the magnitude of Betty's force F B if Charles pulls in (a) the direction drawn in the picture or (b) the other possible direction for equilibrium? Alex Charles 154° Betty

In a 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 É A of magnitude 219 N, and Charles pulls with force
F c of magnitude 187 N. Note that the direction of F c i not given. What is the magnitude of Betty's force F B if Charles
pulls in (a) the direction drawn in the picture or (b) the other possible direction for equilibrium?
