A man 'A' moves in north direction with speed 10m/s and another man B moves in `E-30^(@)-N` with `10 m//s`. Find the relative velocity of `B w.r.t. A.

Explanation

To solve the problem of finding the relative velocity of man B with respect to man A, we can follow these steps:

### Step 1: Define the velocities of A and B
- Man A moves north with a speed of 10 m/s. We can represent this velocity as:
\[ \vec{V_A} = 0 \hat{i} + 10 \hat{j} \quad \text{(where } \hat{i} \text{ is east and } \hat{j} \text{ is north)} \]
