Suppose we go 200 km above and below the surface of the Earth, what are the g values at these two points? In which case, is the value of g small?

Explanation

Given: depth(d) = height(h) = 200 km
We know that R = 6400 km
Formula: `g_("height")=g[1-(2h)/(R)]`
`g_("depth")=g[1-(d)/(R)]`
`thereforeg_("height")=g[1-(2xx200)/(6400)]`
`=g[(64-4)/(64)]=0.937g`
`g_("height")=g[(60)/(64)]=0.94g`
`g_("dept")=g[1-(200)/(6400)]`
`=g[(64-2)/(64)]`
`=g[(62)/(64)]=0.968g`
`g_("depth")=g[0.96]`
