Question

How much A dice of neutron star material would weigh ?

Answer 1

weight on the earth=200w (90kg)

weight=mg=$\frac{GMm}{R^{2}}$

$mg=\frac{(6.67\times10^{-11}\frac{Nm^{2}}{kg^{2}})(2)(2\times10^{30}kg)(90kg)}{(10,000m)^{2}}$

weight$=240$ trillion N

$=240\times10^{12} N$

weight$\approx50 trillion$ pounds
