Assume there are two identical simple pendulum Clocks-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 4s and 6s respectively. Then the value of h is – (consider radius of earth RE = 6400 km and g on earth 10 m/s2 )
(A) 1200 km
(B) 1600 km
(C) 3200 km
(D) 4800 km
