True or False 1. A force vector can be resolved into infinitely many force components. 2. A 50N force directed 69° N of W is equal to -50N force directed 21° E of S. 3. In a force system with two vectors, force A is completely known while only the line of action of force B is known. The resultant R of A+B is minimum if and only if R is perpendicular to B. 4. Vector addition is commutative. They can be added in any order. 5. Two vectors are considered equal as long as they have the same magnitude.
