Suppose a vertical tunnel is dug along the diameter of earth assumed to be a sphere of uniform mass having density \(\rho\). If a body of mass m is thrown in this tunnel, its acceleration at a distance y from the centre is given by
- \(\frac{4 \pi}{3} G \rho y m\)
- \(\frac{3}{4} \pi G \rho y\)
- \(\frac{4}{3} \pi \rho y\)
- \(\frac{4}{3} \pi G \rho y\)
Answer
(D) 4 3 G y
