strength of the Sun at the surface when calculate basic kinematics situations involving gravity as the Sun is too far away to the surface of Earth to have any signincant effects. Mercury, on the other hand, is close enough that the Sun would affect its surface gravity enough to be significant. Calculate the gravitational field strength of Mercury at its surface (ignoring the sun). b. Calculate the gravitational field strength of the Sun at the surface of Mercury (during daytime). Calculate the true value of Mercury's gravitational field strength during the daytime.12C.
