g' = (G * 3M) / (2R)² = 3/4 * (GM/R²) = 3/4 × 9.8 = 7.35 ms⁻² (Note: The provided solution in image uses g' = (M'/R'²) * g = (3M/(2R)²) * g = 3/4 * g = 3/4 × 9.8 = 7.35. However, the printed explanation shows g' = (M/R²) * (2M/(R)²) = 2/9 * g = (9.8 × 2)/9 ms⁻² = 2.2ms⁻². Weight W' = mg' = 1 × 2.2 = 2.2N)
