at what distance from the centre of earth does the gravitational acceleration have one third. the value that it has on the earth surface..
-
1/3 = 1/r^2
r^2 = 3
r = sq rt (3) = 1.7323 earth radii
Earth radius = 6371 km (http://en.wikipedia.org/wiki/Earth_radiu…
r = 1.7323 * 6371 = 11,034.90 km
r^2 = 3
r = sq rt (3) = 1.7323 earth radii
