A planet revolves around the sun in an elliptical orbit of eccentricity e. if T is the time period of the planet, then the time spent by the planet between the ends of the minor axis and major axis close to the sum is.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
As areal velocity of a planet around the sun is constant. Therefore, the desired time is
If a = semi-major axis and b = semi-minor axis of ellipse, then, area of ellipse = 
Area ABS 
(area of ellipse) – Area of triangle ASO
