Two heavy spheres of masses `10^(4)` kg and `10^(6)` kg and each of radius 20 cm are separated by a distance of 100 m. What will be the potential at the mid-point of the joining their centres ?

Explanation

To find the gravitational potential at the midpoint between two heavy spheres, we can follow these steps:

### Step 1: Identify the masses and distance
Let the masses of the two spheres be:
- \( M_1 = 10^4 \, \text{kg} \)
- \( M_2 = 10^6 \, \text{kg} \)

The distance between the centers of the two spheres is given as:
