From: JEE Main 2016 (Online) 9th April Morning Slot
Question
Figure shows elliptical path abcd of a planet around the sun S such that the area of triangle csa is the area of the ellipse. (See figure) With db as the semimajor axis, and ca as the semiminor axis. If t1 is the time taken for planet to go over path abc and t2 for path taken over cda then :

Correct answer
Ct1 = 3t2
Step-by-step explanation
Let the area of ellipse = A
Area of abcSa = = Area of half of the ellipse + Area of the triangle =
Area of adcSa = =
= = 3
t1 = 3t2
Area of abcSa = = Area of half of the ellipse + Area of the triangle =
Area of adcSa = =
= = 3
t1 = 3t2
