Compute the Schwarzschild radius for objects of mass m (kg). Use c = 299,792.458 km/s and G = 6.6738*10^-11 N*(m/kg)^2. Your function should give the result in m.
Please check the answers for the test suite, as I think there may be a unit discrepancy here with c in km/sec and G in N*(m/kg)^2.
Thanks James and Vitor for noticing the mistake! All fixed and rescored...
The Schwarzschild radius is of the order of milimiters for the Earth (8.881e-3 meters) and the order of kilometers for the Sun (2,97024415e3 meters)!
