For a body in circular motion with a constant angular velocity, the magnitude of the average acceleration over a period of half a revolution is … times the magnitude of its instantaneous acceleration.

Options

A. `(2)/(n)`
B. `(n)/(2)`
C. N-W
D. 2

Explanation

To solve the problem, we need to determine the relationship between the average acceleration of a body in circular motion over half a revolution and its instantaneous acceleration. Let's break it down step by step.

### Step 1: Understand the Motion
A body in circular motion with constant angular velocity means that it moves along a circular path at a constant rate of rotation. The angular velocity is denoted by \( \omega \).

### Step 2: Define Initial and Final Velocities
When the body moves from point P to point Q (half a revolution), it has:
- Initial velocity \( \mathbf{v_1} \) at point P.
