Vector A → has a magnitude of 29 units and points in the positive y-direction. When vector B → is added to A → , the resultant vector  A → + B → points in the negative y-direction with a magnitude of 14 units. Find the magnitude and direction of B → .

To determine
The magnitude and direction of the vector B .

Explanation

Given Info: The vector A is having magnitude 29units and directed along positive y-axis.

The resultant vector (R) is having magnitude 14units and directed along negative y-axis. Here, considering, the resultant vector (A+B) as (R) .

Explanation:

The graphical representation of the vectors is given below:

To get the resultant vector of any two vector, the tip of the first vector will starts from the end of the second vector. And the resultant vector starts from the end of the first vector and end up to the tip of the second vector.

The position of the vector (A) is at (0,29)
