Answer 1

Answer

4.8212×10⁻¹¹ N

Explanation

The gravitational force F, between 2 masses m₁ and m₂ is given by:

F = (Gm₁m₂)/d²

Where G =  6.673 x 10⁻¹¹ N m²/kg² and d is the distance between the 2 masses.

F = (Gm₁m₂)/d²

   =  (6.673 x 10⁻¹¹ × 0.425 × 0.425)/0.500²

   = 1.2053×10⁻¹¹/0.25

   = 4.8212×10⁻¹¹ N
