W is the weight of a man on the surface of the earth. What would be his weight, if he goes to a depth (h) equal to the radius of the earth, below the surface of the earth?

Options

A. `W'=(W)/(2)`
B. `W'=0`
C. `W'=(W)/(3)`
D. `W'=(W)/(4)`

Answer

B

Explanation

`g'=g[1-(x)/(R )]` If x = R, then `g' = 0 therefore W' = 0`
