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
