Final answer:
The force on the bracket cannot be determined without more context. For physics problems, calculations for forces depend on given values for friction, normal force, and other applied forces.
Step-by-step explanation:
The force acting on the bracket cannot be determined without additional context or specific details about the scenario in which the bracket is being used. If the question relates to the force acting on an object on a horizontal surface, one could calculate the net force or the force of friction using the coefficient of friction, normal force, and any additional applied forces. For instance, if an object is subjected to equal gravitational and normal forces, and there is also a known frictional force, the acceleration of the object could be calculated, giving insight into any additional applied forces.
