Question

The rate of change of the area swept by the radius vector, \[\frac {ΔA}{Δt}\] ​, is shown to be constant and equal to:

Options

• 2mL

• \[\frac {2m}{L}\]

• \[\frac {L}{2m}\]

• \[\frac {1}{2}\](r × p)

Answer 1

\[\frac {L}{2m}\]

Explanation:

This formula correctly relates the constant rate of area sweep to the conserved angular momentum (L) and the planet's mass (m).
