Question
The figure shows elliptical orbit of a planet m about the sun S. The shaded area SCD is twice the shaded area SAB. If t1 be the time for the planet to move from C to D and t2 is the time to move from A to B, then ;
Options
A.t1 = t2
B.t1 = 8t2
C.t1 = 4t2
D.t1 = 2t2
Solution
From Kepler′s law : Areal velocity = constant so 
⇒ t1 = 2t2
⇒ t1 = 2t2 Create a free account to view solution
