PROBLEM STATEMENT: This problem is still being typed.

SOLUTION: (E) A solar-mass black hole would exert no more gravitational pull than our sun. Thus, the orbits would remain unchanged.

    This question is vague in so many ways. Does the black hole have charge or angular momentum? Is the question considering the effects of, possibly though unrealistic, the sun collapsing into a black hole? If so, there will certainly be a vast gravitational disturbance that will at least minutely affect the orbits of the planets.

    And modifying the question to say “under Newtonian gravity” wouldn’t be better, because black holes don’t even exist in Newtonian gravity.

    This question shouldn’t be on this exam. Shame on the test makers.
