Answer:
Explanation:
Both these questions are based on the Universal Law of Gravitation, which is given by :
F = Gm1m2 / r²
2) F = 6.67 x 10⁻¹¹ x 8 x 10³ x 1.5 x 10³ / 1.5 x 1.5
    F = 6.67 x 10⁻⁵ x 8 / 1.5
    F = 35.57 x 10⁻⁵ N
3) F = 6.67 x 10⁻¹¹ x 7.5 x 10⁵ x 9.2 x 10⁷ / 7.29 x 10⁴
    F = 6.67 x 10⁻³ x 7.5 x 9.2 / 7.29
    F = 63.13 x 10⁻³ N
