If radius of the earth is 6347 km, then what will be difference between acceleration of free falls and acceleration due to gravity near the earth's surface? |

Answer» A. 0.34 `g_("free FALL")=(GM)/(R^(2)-omega^(2)R=9.8-omega^(2)R` `g-g_("free falls")omega^(2)R=((2pi)/(T))^(2)R` `=(4pi^(2))/((24xx60xx60)^(2))xx6347xx10^(3)=0.03401` |
