An apple of mass 250 g falls from a tree. Calculate the acceleration of Earth towards the apple.
Mass of the Earth `=5.983xx10^(24)kg`
Radius of the Earth `=6.378xx10^(6)mandG=6.67xx10^(-11)Nm^(2)kg^(-2)`

Explanation

Here m = 250, g = 0.250 kg,
`R=6.378xx10^(6)m`
Acceleration of Earth towards an apple
`a^(1)=(F)/(M)=(Gm)/(R^2)`
`=((6.67xx10^(-11))xx(0.25))/((6.378xx10^(6))^(2))`
`=4.1xx10^(-25)m//s^(2)`
