Vector `vecA,` which is directed along an x axis, is to be added to vector `vecB,` which has a magnitude of `6.0` m. The sum is a third vector that is directed along the y axis, with a magnitude of `vecA `Find the magnitude of `vecA ` ?

Explanation

To solve the problem step by step, we will analyze the vectors involved and apply the principles of vector addition.

### Step 1: Understand the problem
We have two vectors:
- Vector **A** directed along the x-axis.
- Vector **B** with a magnitude of 6.0 m directed along the y-axis.

The resultant vector **R** is directed along the y-axis and has the same magnitude as vector **A**.
