The figure shows elliptical orbit of a planet $m$ about the sun $S$ . The shaded area SCD is twice the shaded are $SAB$ . It $t_{1}$ is the time for the planet to move from $C$ to $D$ and $t_{2}$ is the time to move from $A$ to $B$ then

Options:

Answer:

Solution:

Kepler's $2^{nd}$ law $\Rightarrow (\frac{Δ A}{Δ t})_{planet} = constant \frac{A _{1}}{t _{1}} = \frac{A _{2}}{t _{2}} \Rightarrow \frac{2 A}{t _{1}} = \frac{A}{t _{2}} \Rightarrow t_{1} = 2 t_{2}$
