The given figure shows the elliptical orbit of a planet ra about the sun S. If t 1 is the time taken by the planet to move from C to D and fa is the time taken by the planet to move from A to B, then the relation between t 2 and fa is [Given, area SCD = 2 (area SAB)]
Text Solution
Verified by ExpertsThe correct answer is:
B
t 1 = 2t 2
According to kepler's second law
Equal areas are swept in equal time, ti, the time taken to go from C to D = 2t 2 where t 2 is the time taken to
go from A to B. As it is given that area
SCD = 2SAB.
