The Schwarzschild radius RBH for an object of mass M is defined as RBH = 2GM/c^2

Question

The Schwarzschild radius RBH for an object of mass M is defined as RBH = 2GM/c^2 where c is the speed of light and G is the universal gravitational constant. RBH gives the radius of the event horizon of a black hole with mass M (in other words, it gives the radius to which some amount of mass M would need to be compressed in order to form a black hole). The mass of the Sun is about 1.99 x 10^30 kg. What would be the radius of a black hole with this mass? Number RBH = m The mass of the Moon is about 7.35 x 10^22 kg. What would be the radius of a black hole with this mass? Number RBH = m Suppose you want to make a black hole that is roughly the size of an atom (take RBH = 1.30 x 10^-10 m). What would be the mass M of such a black hole? Number M = kg

Explanation / Answer

RBH=2949.62m;

RBH=0.0001089

;M=8.77*10^16
