After our Sun exhausts its nuclear fuel, its ultimate fate may be to collapse to a white dwarf state, in which it has approximately the same mass as it has now but a radius equal to roughly the size of the Earth's radius. (a) Calculate the average density of this white dwarf if the Sun were to collapse to a radius of 6.31 × 10°m. 1.84e+9 Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. kg/m (b) Calculate the free-fall acceleration at its surface. 3.27e+6 m/s2 (c) Calculate the gravitational potential energy of a 4.00 kg object at its surface. (Take U, = 0 at infinity.) -8.33e+13 Need Help? Read It
