Compute the differential tidal force AF exerted on the Earth by Mars
when it's at opposition. Express your result as a numerical fraction of the
differential tidal force exerted by the Moon,
2GMMoonm RO
where ro = 384,000km = 0.00257AU is the Earth-Moon distance and MMoon = 7.2
x 1022kg is the mass of the Moon. Repeat to find the differential tidal force AF
exerted by Jupiter at opposition, also expressed as a fraction of AEMaen.
(Assume that the Moon, Earth, Mars, and Jupiter are on circular coplanar
orbits.)

- Consider Figure 13.23 in Tidal Forces. This diagram represents the tidal forces for spring tides. Sketch a similar diagram for neap tides. (Hint: For simplicity, imagine that the Sun and the Moon contribute equally. Your diagram would be the vector sum of two force fields (as in Figure 13.23), reduced by a factor of two, and superimposed at right angles.)arrow_forwardA)At what altitude would a geostationary sattelite need to be above the surface of Mars?
