Figure elliptical path abed of a planet around the sun S such that the area of Delta csa is `(1)/(4)` the area of the ellipse, (see figure) with db as the semimajor axis, and ca as the semiminor axis if `t_(1)` is the time taken for planet to go over path abc and `t_(2)` for path taken over cda then:A. `t_(1)=3t_(2)`B. `t_(1)=t_(2)`C. `t_(1)=2t_(2)`D. `t_(1)=4t_(2)` |

Answer» Correct Answer - A Total area `=A` Area of `sabc=(3A)/A` Area of `sadc=A/4` `(3A)/(4t_(1))=A/(4t_(2))impliest_(1)=3t_(2)` |
