Journey through the center of earth:
Suppose you could dig a tunnel from one surface to the opposite through the centre of the Earth. How will the journey be through the tunnel? Let us assume that the Earth to be of uniform density, there is no air friction and temperature is normal. At the starting point the initial acceleration will be g = 9.8 m/s2.
The acceleration gradually reduces as one approaches the center.
The gravity at any radius reff is less than REarth and is linearly proportional to the distance from the center. So, the weight will goes on reducing as the centre is approached. It will again goes on increasing as one moves from away from the centre. The traveller will pop up on the opposite side of the Earth within 42 minutes approximately. But unless the traveller grabs something to hold on, he or she will fall back for a return journey and continue to oscillate with a round-trip time. The time period will be
How the acceleration due to gravity varies inside the tunnel?
  • a)
    Acceleration due to gravity remains constant throughout.
  • b)
    Acceleration due to gravity increases as one approaches the centre. It is maximum at the centre. It again starts reducing as one moves away from the centre.
  • c)
    Acceleration due to gravity decreases as one approaches the centre. It is zero at the centre. It again starts increasing as one moves away from the centre.
  • d)
    Acceleration due to gravity is unpredictable.
Correct answer is option 'C'. Can you explain this answer?

So, as reff decreases, gff decreases. At centre reff = 0 and hence geff is also 0. So, Acceleration due to gravity decreases as one approaches the centre. It is zero at the centre. It again starts increasing as one moves away from the centre.
