Short Answer

Expert verified

Part (a)

Part (b)

Step by step solution

01

Part (a)

Place the tail of vector B→on the tip of vector A→and then connect the tail of vector A→with the tip of the vector B→as shown below


02

Part (b)

To find A→−B→=A→+(−B→), place the tail of vector −B→on the tip of vector A→and then connect the tail of A→vector with the tip of the vector (−B→)as shown below:
