If \(A\) is the areal velocity of a planet of mass \(M\), its angular momentum is
- A \(\frac{M}{A}\)
- B \(2 M A\)
- C \(A^2 M\)
- D \(A M^2\)
Answer & Solution
Correct Answer
(B) \(2 M A\)
Step-by-step Solution
Detailed explanation
According to Kepler's law of area, the areal velocity is given by \(A=\frac{L}{2 M}\) where, \(L=\) angular momentum, \(M=\) mass of planet and \(\quad A=\) areal velocity. Then, \(L=2 M A\)
