JEE Main 28 July 2022, Shift 2, Physics Q6

Question 6 of 90 in this shift, Physics question 6 of 30, Section A.

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

\mathrm{R_E}

= 6400 km and g on earth

10\ \mathrm{m/s^2}

)

(1)1200 km
(2)1600 km
