A block B of mass m (see Figure 1) can slide freely on a frictionless arm OA which rotates in a horizontal plane at a constant rate B is released at a distance ro from O. And moves toward A located at a distance ra from O. What is the magnitude of the angular momentum, about O, of Block B at a distance r between B and A? The answer should be in terms of the given parameters. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

Read and Solve carefully please Write clearly and Box the Final answer(s) Express your answer to 3 Significant figures and include appropriate units.
A block \( B \) of mass \( m \) (see Figure 1) can slide freely on a frictionless arm \( OA \) which rotates in a horizontal plane at a constant rate \( \dot{\theta}_O \). \( B \) is released at a distance \( r_O \) from \( O \). And moves toward \( A \) located at a distance \( r_A \) from \( O \).

What is the magnitude of the angular momentum, about \( O \), of Block \( B \) at a distance \( r \) between \( B \) and \( A \)? The answer should be in terms of the given parameters.

For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
