Salam sir !why we take squre of (r) in the gravitation formula

[@physicskasafar]

Walaikum salam By experiment it was observed that when distance is doubled between two masses than gravitational force decreased 4 times . And when distance is 3 times the initial value then force decreased 9 times of it's initial value That's why wo take r square
