Assume a neutron star has a mass of about 1.2 times the mass of the Sun and a radius of 7 kilometers.
a) Calculate the average density of a neutron star, in kilograms per cubic centimeter.
b) If the escape speed is V2esc=2GM/R, work out the formula for the radius of the Event Horizon around a Black Hole of mass M.
c) Assume the Even Horizon is the size of the Black Hole. What is the density of a Black Hole that has the mass of the Sun?
d) What would be the mass of a Black Hole that has a diameter of 1 cm? Compare it to the mass of Mount Everest (about 5 x 1010 kg).
