Two heavy point masses of mass `10^(3)` kg and `10^(5)` kg are separated by a distance of 200 m. What will be the potential at the mid-point of the line joining them ?

Explanation

To find the gravitational potential at the midpoint of the line joining two point masses, we can follow these steps:

### Given:
- Mass \( m_1 = 10^3 \, \text{kg} \)
- Mass \( m_2 = 10^5 \, \text{kg} \)
- Distance between the masses \( d = 200 \, \text{m} \)

### Step 1: Identify the midpoint
