The figure shows the motion of a planet around the sun in an elliptical orbit with the sun at the focus. The shaded areas A and B are also shown in the figure which can be assumed to be equal. If t1 and t2 represent the time for the planet to move from a to b and d to c respectively, then
1
t1 < t2
2
t1 > t2
3
t1 = t2
4
t1 ≤ t2
