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 4s and 6s respectively. Then the value of h is – (consider radius of earth RE = 6400km and g on earth 10 m/s2)

Option 1 -

1200 km

Option 2 -

1600 km

Option 3 -

3200 km

Option 4 -

4800 km

g = A x x 2 + a 2 3 / 2  

v 0 ? d V = - x ? g d x

O - V = - A x a 2 + x 2 3 / 2

Let, a 2 + x 2 = t 2

2 x d x = 2 t d t

x d x = t d t

V = A t d t t 3 - A t - A a 2 + x 2 x

V = A a 2 + x 2

 g'=gω2Rsinθ

g' (atθ=0pole)=g

g' (atθ=90°, equator)=gω2R

g decreases as we move bole to equator

So, A is false statement

But ‘R’ statement is true
