Calculate the force of gravitation due to earth on a ball of 1 kg mass lying on the ground.( given mass of earth is 6*10 to the power 24 and radius of the

earth is 6.4*10 to the power 3 and G= 6.67*10 to the power -11


Using the formula  g=Gm1m2/Rsquare....
and substituting values.. we get g=9.8N

F=GMm /R^2  M=Mass of the earth =6 x10*24kg  m=mass of the body=1kg,R= Radius of the earth=6.4 x10*3m,G=Gravitational constant=6.67 x10*-11Nm*2/kg*2   then F=6.67 x10*-11x6 x10*24 x1/6.4 x6.4 x10*3 x10*3 =6.67 x6 x10*13/6.4 x6.4 x10*6 =667 x6 x10*7/64 x64=0.97705 x10*7 =9.7705 x10*6N
