In the following four Periods,
(i) Time of revolution of a satellite just above the earth's surface $\left({\mathrm{T}}_{\mathrm{st}}\right)$
(ii) Period of oscillation of mass inside the tunnel bored along the diameter of the earth $\left({\mathrm{T}}_{\mathrm{ma}}\right)$
(iii) Period of simple pendulum having a length equal to the earth's radius in a uniform field of 9.8 N/kg $\left({\mathrm{T}}_{\mathrm{sp}}\right)$
(iv) Period of an infinite length simple pendulum in the earth's real gravitational field $\left({\mathrm{T}}_{\mathrm{is}}\right)$

• A

  ${\mathrm{T}}_{\mathrm{st}}>{\mathrm{T}}_{\mathrm{ma}}$

• B

  ${\mathrm{T}}_{\mathrm{ma}}>{\mathrm{T}}_{\mathrm{st}}$

• C

  ${\mathrm{T}}_{\mathrm{sp}}<{\mathrm{T}}_{\text{is }}$

• D

  ${\mathrm{T}}_{\mathrm{st}}={\mathrm{T}}_{\mathrm{ma}}={\mathrm{T}}_{\mathrm{sp}}={\mathrm{T}}_{\mathrm{is}}$
