A spacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 1260 kg. It has strayed too close to a black whole having a mass 99 times that of the Sun. The nose of the spacecraft points toward the black hole, and the distance among 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 dissimilarity 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 dissimilarity in acceleration grows quickly as the ship approaches the black hole. It puts the body of the ship under extreme tension and eventually tears it apart.
