The tidal force is a differential force: dF/dr, which is the difference between the force at one distance and the force at another. If dr happens to correspond to, say, your height, then the tidal force is the difference in gravity felt by your head and by your feet. This amounts to a stretching force, since one end is pulled harder than the other end. Calculate the tidal force experienced by your body at the surface of a neutron star. Assume that the neutron star has a mass of 1.5 solar masses and a radius of 10 km. Assume that your mass is 100 kg and that your dr (height) is 2 m when standing and 0.5 m when prone. What is the tidal force when you are standing? What is the tidal force when you are prone? Based on the above, what do you recommend for minimizing the tidal force?

Question
  1. The tidal force is a differential force: dF/dr, which is the difference between the force at one distance and the force at another. If dr happens to correspond to, say, your height, then the tidal force is the difference in gravity felt by your head and by your feet. This amounts to a stretching force, since one end is pulled harder than the other end. Calculate the tidal force experienced by your body at the surface of a neutron star. Assume that the neutron star has a mass of 1.5 solar masses and a radius of 10 km. Assume that your mass is 100 kg and that your dr (height) is 2 m when standing and 0.5 m when prone.

    1. What is the tidal force when you are standing?

    2. What is the tidal force when you are prone?

    3. Based on the above, what do you recommend for minimizing the tidal force?
