The change in the value of g at a height 'h' above the surface of earth is the same as at a depth 'd' below the surface of earth. When both d and h are much smaller than the radius of earth, then which one of the following is correct? |
|
Answer» `d=(h)/(2)` `g.=g(1-(2h)/(R )) rArr Delta g_(1)=(2h)/(R ).g` At DEPTH d below the surface of earth `g.=g(1-(d)/(R )) rArr Delta g_(2)=(d)/(R ).g` since `Deltag_(1)=Delta g_(2) rArr d=2h`. So the correct CHOICE is (c ). |
