Question

The areal velocity and the angular momentum of the planet are related by which of the following relations?
(where $m_p$ is the mass of the planet)

• A. $\frac{\Delta\vec{A}}{\Delta t} = \frac{\vec{L}}{2m_{p}}$
• B. $\frac{\Delta\vec{A}}{\Delta t} = \frac{\vec{L}}{m_{p}}$
• C. $\frac{\Delta\vec{A}}{\Delta t} = \frac2{\vec{L}}{2m_{p}}$
• D. $\frac{\Delta\vec{A}}{\Delta t} = \frac{\vec{L}}{\sqrt{2}m_{p}}$

Answer 1

Answer: (A)

Areal velocity and linear momentum of the planet is related by the relation
$\frac{\Delta\vec{A}}{\Delta t} = \frac{\vec{L}}{2m_{p}}$
