Question

Most of the blackholes observed by astronomers have masses equal to a few solar masses (the result of the death of a high mass star) or have masses equal to several million solar masses (found at the core of most galaxies). Recently, a third category of blackhole has been observed with a mass between these two extremes. Calculate the Schwarzschild radius of a blackhole that has a total mass equal to 125 solar masses.

Explanation / Answer

20 solar masses = (1.98892 x 10^30) x 125 = 24.8615
