Question

If a 5-solar-mass black hole has a radius to its event horizon of 15 km, the radius of the event horizon of a 50-solar-mass black hole will be __________ km.

Answer 1

Answer:150km

Step-by-step explanation:

A 5-solar-mass black hole has radius to its event horizon to be 15 km, then the radius of the event horizon of a 50-solar-mass black hole will be

5solarmass =15km

50solar mass = x

Cross mutiply

x = 50* 15 / 5

15 x 10 = 150km
