Question

In planetary motion the areal velocity of position vector of a planet depends on angular velocity (ω) and the distance of the planet from sun (r). If so the correct relation for areal velocity is

Options :

  1. (dA/dt) ∝ ωr

  2. (dA/dt) ∝ ω²r

  3. (dA/dt) ∝ ωr²

  4. (dA/dt) ∝ √(ωr)

Show Answer
