Two bodies A and B having masses 20kg and 40kg are separated by 10 m. at what distance from body a should another body C of mass 15 kg be placed so that net gravitational force on C is zero?

Explanation

To solve the problem, we need to find the position of body C such that the net gravitational force acting on it due to bodies A and B is zero. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Setup
We have:
- Mass of body A (m_A) = 20 kg
- Mass of body B (m_B) = 40 kg
- Distance between A and B = 10 m
- Mass of body C (m_C) = 15 kg
