Assuming the earth to be a sphere of uniform mass density, how much would a body weigh half way down to the centre of the earth if it weighed 250 N on the surface ?

Text Solution

Verified by Experts

As `g_(d)=g(1-(d)/(R)) implies mg_(d) = mg(1-(d)/(R))`
Here `d=(R)/(2)`
`:. mg_(d) = (250) xx (1-(R // 2)/(R)) = 250 xx (1)/(2) = 125 N`
