Key Points

• Aravali range​
  • The Aravallis of Northwestern India, one of the oldest fold mountains of the world, now form residual mountains with an elevation of 300m. to 900m.
  • They stretch for a distance of 800 km from Himmatnagar in Gujarat to Delhi, spanning Haryana, Rajasthan, Gujarat, and Delhi, the 692 kilometres (km).

  • The Aravallis date back to millions of years when a pre-Indian sub-continent collided with the mainland Eurasian Plate.
  • Carbon dating has shown that copper and other metals mined in the ranges date back to at least the 5th century BC.

The correct answer is option 4) i.e. ∞

CONCEPT:

• ​The time period of a pendulum is given by the equation:

​\(\Rightarrow T = 2\pi\sqrt{\frac {L}{g}}\)

Where L is the length of the string of pendulum and g is the acceleration due to gravity.

EXPLANATION:

• At a height of 900 km from the earth's surface gravity is absent.

Therefore, g = 0.

Substituting g = 0,

\(\Rightarrow T = 2\pi\sqrt{\frac {L}{0}} = ∞\)

Thus, the time period of the pendulum at a distance of 900 km from the Earth will be infinite.
