(1) With a neat labelled diagram, how the value of g changes while going deep inside the earth.​

Answer»

here is the answer!!!!

There are 3 factors:

  • Nearer to earth center, there is LESS mass that contributes to the FORCE of gravity (as NEWTON showed the outer shell of mass contributes NET force of zero).
  • The DISTANCE to the center of gravity of earth reduces.
  • Deeper down, the density (mass per volume) will increase.
