Figure (11-Q2) shows the elliptical path of a planet about the sun. The two shaded parts have equal area. If t1 and t2 be the time taken by the planet to go from a to b and from c to d respectively,
(a) t1 < t2
(b) t1 = t2
(c) t1 > t2
(d) insufficient information to deduce the relation between t1 and t2.
