SUMMARY
The gravity on the surface of the Earth, if its mass were doubled and its radius halved, would be calculated using Newton's law of universal gravitation. Specifically, the gravitational force can be expressed as F = G * (m1 * m2) / r². Doubling the mass (m1) and halving the radius (r) results in an increase in gravitational force by a factor of 16, due to the inverse square law. This scenario leads to a significant increase in density, raising questions about the feasibility of such a planet's formation.
