(a) What is the approximate force of gravity on a 70-kg person due to the Andromeda Galaxy, assuming its total mass is 1013 that of our Sun and acts like a single mass 0.613 Mpc away? (b) What is the ratio of this force to the person’s weight? Note that Andromeda is the closest large galaxy.
A spacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 1 000 kg. Ii has strayed too close to a black hole having a mass 100 times that of the Sun (Fig. P11.11). The nose of the spacecraft points toward the black hole, and the distance between the nose and the center of the black hole is 10.0 km. (a) Determine the total force on the spacecraft. (b) What is the difference in the gravitational fields acting on the occupants in the nose of the ship and on those in the rear of the ship, farthest from the black hole? (This difference in accelerations grows rapidly as the ship approaches the black hole. It puts the body of the ship under extreme tension and eventually tears it apart.)
The Schwarzschild radius RBH for an object of mass M is defined as (See image.) where c is the speed of light and G is the universal gravitational constant. RBH gives the radius of the event horizon of a black hole with mass M. In other words, it gives the radius to which some amount of mass M would need to be compressed in order to form a black hole. 1. The mass of the Sun is about 1.99 × 1030 kg. What would be the radius of a black hole with this mass? 2. The mass of Mars is about 6.42 × 1023 kg. What would be the radius of a black hole with this mass? 3. Suppose you want to make a black hole that is roughly the size of an atom (take RBH = 1.10 x 10-10 m). What would be the mass M of such a black hole?

AI answered the problem this way. Is this correct? The Lorentz force that makes a charged particle move in a circular path in a magnetic field is given by F=qvBF=qvB where qq is the charge of the particle, vv is the speed of the particle, and BB is the magnetic field strength. Since the particle is moving in a circular path, this force must equal the centripetal force, F=mv2rF=rmv2, where mm is the mass of the particle and rr is the radius of the circular path. Setting the two expressions for FF equal to each other, we get qvB=mv2rqvB=rmv2 Since we want to find the frequency of the orbit, we need to find the speed vv of the proton. Given that the energy of the proton is 1 MeV, we can write 12mv2=1 MeV21mv2=1MeV and solve for vv: v=2×1 MeVmv=m2×1MeV where mm is the mass of a proton, which is approximately 1.67×10−27 kg1.67×10−27kg. Substituting this expression for vv into the expression for the Lorentz force, we can solve for the frequency of the orbit. The frequency is related to…
The radius Rh of a black hole is the radius of a mathematicalsphere, called the event horizon, that is centered on the blackhole. Information from events inside the event horizon cannotreach the outside world. According to Einstein’s general theory ofrelativity, Rh = 2GM/c2, where M is the mass of the black hole andc is the speed of light.Suppose that you wish to study a black hole near it, at a radialdistance of 50Rh. However, you do not want the difference in gravitationalacceleration between your feet and your head to exceed10 m/s2 when you are feet down (or head down) toward the blackhole. (a) As a multiple of our Sun’s mass MS, approximately what isthe limit to the mass of the black hole you can tolerate at the givenradial distance? (You need to estimate your height.) (b) Is the limitan upper limit (you can tolerate smaller masses) or a lower limit(you can tolerate larger masses)?

Consider a region where the electric field and the magnetic field are along the +x- and the -y-axes, respectively. If a certain charge is in the region, at what velocity should it move so that it will move in a uniform velocity? (To maintain a uniform velocity, the Lorentz force must be zero) Let E and B be the magnitudes of the electric field and of the magnetic field, respectively. B V = - - B E az V = E V = az 1>
