A black hole is a collapsed star. The gravity of a black hole is so strong that not even light can escape from within its surface or "event horizon". Even outside that surface, enormous energies are needed to escape. Suppose that you are 10 km away from the centre of a black hole (m=10 kg). if your mass is 70 kg, how much do you weigh?

Show calculation!

This black hole has mass of just 10 kg? If so:

W = G*m1*m2/r^2
where G (the universal gravitation constant) = 6.67*10^11 nt*m^2 / kg^2

All the data needed are not here. So we can say the weight is ∞
