Acceleration due to gravity below the earth surface is given by:g' = g1-dRwhere d is the depth below the earth surfacea) g' = 36% of gg' = 36100gg1-dR = 36100g1-36100 = dR64100 = dRd = 64100Rtherefore below the 64% of R 
b) g' = g - 36% of gg' = g-36100gg' = 64100gg1-dR=64100g1-64100 = dRd = 36100Rtherefore 36% of R below the earth surface

how much below the surface of earth does the acceleration due to gravity a) reduce to 36% b)reduces by 36% of its value on the surface of earth.
