A and B are moving with the same speed 10m/s in the direction `E-30^(@)-N` and `E-30^(@)-S` respectively. Find the relative velocity of `A w.r.t. B.

Explanation

To find the relative velocity of A with respect to B, we will follow these steps:

### Step 1: Understand the Directions
A is moving in the direction of East 30° North, and B is moving in the direction of East 30° South. We need to break down their velocities into components.

### Step 2: Define the Coordinate System
- East is taken as the positive x-direction (i cap).
- North is taken as the positive y-direction (j cap).
