Assume there are two identical simple pendulum clocks. Clock – 1 is placed on the earth and Clock - 2 is placed on a space station located at a height h above the earth surface. Clock – 1 and Clock – 2 operate at time periods 4 s and 6 s respectively. Then the value of h is- (consider radius of earth RE = 6400 km and g on earth 10 m/s 2 )

1. 1200 km
2. 1600 km
3. 3200 km
4. 4800 km

Correct answer: 3200 km
