Planet A has a mass of 2.25 × 1020 kg, while planet B has a mass of 6.20 × 1018 kg. What is the gravitational attraction between two planets if the distance between them is 435,500 km? Estimate G as 6.67 × 10-11 N (m/kg) ²

According to Laws of Gravitational attraction,
F = GMm / r²
Given, G = 6.67 * 10^ -11 Nm²/kg²
M = 6.20*10^18 kg.
m = 2.25*10^20 kg
r = 43550000m.
Now
F = 6.67 * 10^ -11 * 6.20*10^18*2.25*10^20 /(435500000)²
= 93.014 * 10^27 / /(435500000)²
= 4.91*10^11N
