How does the quantity of gravitational force on a binary companion change when a 6-solar-mass star becomes a 6-solar-mass black hole?
A) It increases.
B) It decreases.
C) It remains the same.
D) It is impossible to determine.

Question

Quizplus · Accepted Answer

The gravitational force a binary companion experiences depends on the mass of the objects and the distance between them. Since the mass of the star remains the same (6 solar masses) before and after becoming a black hole, and assuming the distance to the companion does not change, the quantity of gravitational force remains the same.
