Question 96 of 223

Assuming the earth to be a sphere of uniform density, the acceleration due to gravity inside the earth at a distance of $r$ from the centre is proportional to

A$r$B$r^{-1}$C$r^2$D$r^{-2}$

Show answer and solution▾

Answer: (A) $r$

Acceleration due to gravity at depth d from the surface of the earth or at a distance $r$ from the centre ' $O$ ' of the earth $g^{\prime}=\frac{4}{3} \pi \rho G r$ Hence $g^{\prime} \propto r$
