Vector A → has a magnitude of 8.00 units and makes an angle of 45.0° with the positive x-axis. Vector B → also has a magnitude of 8.00 units and is directed along the negative x-axis. Using graphical methods, find (a) the vector sum A → + B → and (b) the vector difference A → − B → .

(a)

To determine
The vector sum of (A+B) by using graphical method.

Explanation

Given Info: The vector (A) is having magnitude 8units and makes an angle with positive x axis of 45° .

Explanation:

The vector (B) is having magnitude 8units and makes an angle with negative x-axis.

From graphical method, the vector representation of vector (A) and (B) is,

The end vector (B) is placed at the head of the vector (A)

(b)

To determine
The vector difference of (AB) by using graphical method.
