Neutron stars, such as the one at the center of the Crab Nebula, have about the same mass as our sun, but a much smaller diameter. If you weigh 675 $\mathrm{N}$ on the earth, what would you weigh on the surface of a neutron star that has the same mass as our sun and a diameter of 20.0 $\mathrm{km} ?$

right. So problem, charity one is very similar to problem 39 So if you could you come to a nine. This one should also be very doable. Um, so we're gonna look at the new Zhan star and see how much the weight and given human being waits on earth and how it compares to you, Uh, wait on that new action star. So, first of all, um, this given person, which actually is you with 675 mutants on earth. And so So that's the wave, which we know is they call it, too. The craft Daschle force on Earth. This is simply equals mg. So we can extract mass from that because she is dead. Gravitational constant at the surface of the earth. 9.8. So 6.75 Newton's divided by 9.8 years per second squared. That gives us a mass of 68.88 kilograms. Great. And, uh, we want to know the the weight of that same person on pollution star. So the weight is grafted force again. G times. Um, the mass of the person times the mass of a star, right. Like that Well, actually, these are the mass of stories. The same is the mass of the sun. Just great. And they see the diameter of 20 kilometers. So Diamond Rio equals 20 commoners. Radius will best be 10 kilometers or 10 to 4 meters. That's what I'm gonna write here, uh, variables on me first. And then we can replace with numbers. So a six point 674 I'm just empty minus woman on you didn't meters squared per kilogram squared. That's Fergie. Then the mass of person succeed 0.8 kilogram. The massive sun is 1.9 times 10 to the 30 kilograms and r squared will be four years squared. All right, crunch those numbers down and you will get that the wave, um on the surface of Venusian store has the same miss. Some is, um, nine 0.16 times tend to the church teen Yu Tyne, which is insane. So this would probably an unfortunately crush
