Two planets, Planet A and Planet B, are in space far from other celestial bodies. Planet A has a mass of 5 x 10²⁴ kg and Planet B has a mass of 3 x 10²⁴ kg. They are separated by a distance of 10⁸ meters. Calculate the gravitational force between these two planets. Use the gravitational constant G = 6.674 x 10⁻¹¹ Nm²/kg²
