Answer:

A) 7×10⁻⁸ N

Explanation:

r = Distance between the two skaters = 2 m

m₁ = m₂ = Mass of the two skaters = 65 kg

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

From Newton's Law of Universal gravity

[tex]F=G\frac{m_1m_2}{r^2}\\\Rightarrow F=6.67\times 10^{-11} \frac{65\times 65}{2^2}\\\Rightarrow F=7.045\times 10^{-8}\ N[/tex]

∴ Force of gravity between the two skaters is 7×10⁻⁸ N
