A body of mass 30 kg attracts another body of mass 20 kg with force F. Find the value of F if distance between the centres of two bodies is 30 cm.

Text Solution

AI Generated Solution

To find the gravitational force \( F \) between two bodies, we can use Newton's law of universal gravitation, which states: \[ F = \frac{G \cdot m_1 \cdot m_2}{r^2} \] Where: - \( F \) is the gravitational force, ...
