If A is the areal velocity of a planet of mass M , its angular momentum is

Options

  1. AM A
  2. B2MA
  3. CA^2 M
  4. DA M^2

Correct answer

B. 2MA

Step-by-step solution

Areal velocity A= 1 2 R^2 Multiplying by M on both sides aligned M A & = 1 2 M R^2 M A & = 1 2 I aligned I= moment of inertia. M A= 1 2 L where, L= angular momentum array rlrl & =I & L & =2 M A array
