The problem asks for the gravitational force between two masses and to express it in the form a.b × 10^c with a, b, c chosen from given options. First, recall the gravitational force formula: F = G * (m1 * m2) / r^2, where G ≈ 6.67 × 10^-11 N·m^2/kg^2, m1 = 65.1 kg, m2 = 71.0 kg, and r = 2.50 m. This leads to F ≈ (6.67 × 10^-11) * (65.1 × 71.0) / (2.50)^2. Now consider the products and powers: 65.1 × 71.0 ≈ 4622.1, and (2.50)^2 = 6.25. So F ≈ (6.67 × 10^-11) × 4622.1 / 6.25.
