Two bodies of masses 1kg and 2kg are lying in xy plane at (-1,2) and (2,4) respectively. What are the coordinates of the center of mass?

Explanation

To find the coordinates of the center of mass of two bodies with given masses and positions, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the masses and their positions:**
- Mass \( m_1 = 1 \, \text{kg} \) at position \( r_1 = (-1, 2) \)
- Mass \( m_2 = 2 \, \text{kg} \) at position \( r_2 = (2, 4) \)
