A clock $S$ is based on oscillations of a spring and a clock $P$ is based on pendulum motion. Both clocks run at the same rate on earth. On a planet having same density as earth but twice the radius then

  • A

    $S$ will run faster than $P$

  • B

    $P$ will fun faster than $S$

  • C

    Both run at same rate

  • D

    Both runat same rate but different than earth
