Given:
m₁ = 8 x 10²⁴ kg, mass of planet A
m₂ = 10²⁵ kg, mass f planet B
d = 3 x 10⁷ m, the distance between planets A and B
The gravitational force between planets A and B is
[tex]F=G \frac{m_{1}m_{2}}{d^{2}} [/tex]
where
G = 6.674 x 10⁻¹¹ (N-m²)/kg²
That is,
F =[ (6.674 x 10⁻¹¹ (N-m²)/kg²)*(8 x 10²⁴ kg)*(10²⁵ kg) ]/(3 x 10⁷ m)²
= 5.9324 x 10²⁴ N
Answer:
Planet A exerts a force of 5.9324 x 10²⁴ N on planet B.
Planet B exerts an equal and opposite force om planet A.
