SUMMARY

The discussion centers on the gravitational effects of a hypothetical scenario where the Sun collapses into a black hole. It is established that if the Sun were to become a black hole while retaining its current mass, the gravitational attraction experienced by Earth would remain unchanged. The gravitational force is governed by Newton's law of universal gravitation, expressed as F = G(m1*m2)/r^2, where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers. Therefore, the correct answer to the posed question is that the gravitational attraction would be the same.

PREREQUISITES
  • Understanding of Newton's law of universal gravitation
  • Basic knowledge of black hole properties
  • Familiarity with mass-energy equivalence
  • Concept of gravitational fields
NEXT STEPS
  • Study the implications of mass in black holes and their gravitational influence
  • Learn about the properties and formation of black holes
  • Explore gravitational field equations and their applications
  • Investigate the effects of mass changes on gravitational attraction
USEFUL FOR

Students in physics, astrophysics enthusiasts, and anyone interested in understanding gravitational forces and black hole dynamics.

Hi,
I am currently enrolled in a physics 101 class and I am trying to understand a concept/question.

"If the sun collapsed into a black hole, the Earth gravitational attraction would be
a.same,b.more,c.less,d.none of these

I don't even know where to start, we never even went over black holes never mind the gravitational atrraction between them and another object.

I know Gm1m2/r^2 . but i don't know if a planet/star were changed into a black hole what happens to the mass.
thank you for helping.

You can only assume that the black hole would have the same mass of the sun as it exists today (There is no indication that the sun will ever become a black hole, but this problem only is a 'what if' question, so it doesn't matter).
