Where the weight of a man is more ? at the surface of the earth or at it’s centre ?

Explanation

The value of g at a depth`R//2`from the surface of the earth is`g'=g[g-(d/R]
g'=g[1-(R/2R)=g/2`
The weight of the body=mg'=100/2=50N`
the earth is`g'=g[1-d/R]g'=g[1-R/(2R)]=R/2`The weight of the body `=mg'100/2=50N`
