Calculate the force of gravitation due to earth on a ball of 1 kg mass lying on the ground. ( Given mass of earth= 6 x 1024 kg, Radius of earth = 6.4 x 10​3 km and G= 6.7 x 10​-11 Nm​2  kg​-2​.

Dear Student ,
Here the force of gravitation due to earth is ,
FG=GMemRe2=6·7×10-11×6×1024×16·4×1062=9·81 N
