JEE PYQ: Gravitation Question 41
Question 41 - 2019 (09 Jan Shift 1)
If the angular momentum of a planet of mass $m$, moving around the Sun in a circular orbit is $L$, about the center of the Sun, its areal velocity is:
(1) $\frac{L}{m}$
(2) $\frac{4L}{m}$
(3) $\frac{L}{2m}$
(4) $\frac{2L}{m}$
Show Answer
Answer: (3)
Solution
Areal velocity $= \frac{dA}{dt} = \frac{L}{2m}$.
