Initial and final states of a contracting planet with constant mass.
Initial and final states of a contracting planet with constant mass.
A hypothetical planet is observed to have an initial mass \(M\) and an initial radius \(R\), resulting in a gravitational field strength of \(g_0\) at its surface. Due to a unique geological event, the planet contracts such that its radius becomes \(R/2\) while its total mass \(M\) remains unchanged. What is the new gravitational field strength at the surface of the planet?
