A) 1 cm
B) 1 m
C) 1 km
D) 10 km
E) 200 km

Question

Quizplus · Accepted Answer

The Schwarzschild radius of a non-rotating black hole with the mass of the Earth can be calculated using the formula Rs = 2GM/c^2, where G is the gravitational constant, M is the mass of the Earth, and c is the speed of light. Plugging in values, we get Rs = 1.5 cm. Therefore, the closest answer choice is A) 1 cm.
