How does the force of attraction between the two bodies depend upon their masses and distance between them ? A student thought that two bricks tied together would fall faster than a single one under the action of gravity. Do you agree with his hypothesis or not ? comment.

Explanation

To solve the question step by step, we will break it down into two parts:

### Part 1: Force of Attraction Between Two Bodies

1. **Understanding Gravitational Force**:
The gravitational force (F) between two bodies is given by Newton's law of universal gravitation. The formula is:
\[
F = \frac{G \cdot m_1 \cdot m_2}{R^2}
