What would happen to the gravitational force on Earth if the Sun were to be replaced by a 1-M_ε black hole?

Question

Quizplus · Accepted Answer

The gravitational force a planet experiences from a celestial body depends on the mass of that body and the distance between them. If the Sun were replaced by a black hole of the same mass (1 solar mass), the gravitational force exerted on Earth would remain unchanged, as both the mass of the new black hole and the distance between Earth and the black hole would be the same as they were with the Sun.
