If the value of gravitational acceleration at a height h above the Earth's surface is the same as that at a depth d below the Earth's surface (with both h and d small compared to the Earth's radius R), then |

 | The figure shows the elliptical orbit of a planet with the Sun at the focus. The areas of regions 1 and 2 are the same. If the planet takes times t1 to go from one end to the other end of region 1 and t2 to go from one end to the other end of region 2, then what is the relationship between t1 and t2? | |
