    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
