A black hole,originally with a mass of 10³ MSᵤn,accretes gas and grows so that its event horizon increases in radius by a factor of 10.What is the final mass of the black hole?

Question

Quizplus · Accepted Answer

The radius of a black hole's event horizon is directly proportional to its mass. If the radius increases by a factor of 10, the mass also increases by a factor of 10, resulting in a final mass of 10⁴ M_Sun.
