Problem

Determine the acceleration (both due to gravitational and centrifugal forces) on the surface of a neutron star based on what lattitude we are. How large would the tidal forces acting on an object of height

h=1\;\mathrm{m}

and with a mass

m=1\;\mathrm{kg}

in the vicinity of it surface be? What would the energy of a marshmallow be if it fell to the surface from a height of

h?

The neutron star has a radius of

R

and rotates with a period of

T

. You can consider it spherical even though it is not precisely spherical. Find values that are typical for neutron stars and give general as well as concrete numerical answers.
