Motion of the rigid body is observed from an inertial frame of reference. Rigid body is rotating with constant angular speed about a fixed vertical axis. If we consider a particle of the rigid body not lying on its axis of rotation then net force acting on this particle is.

Options

A. parallel to axis of rotation
B. perpendicular to the axis of rotation and intersecting with it
C. perpendicular to the axis of rotation and not intersecting with it
D. none of these

Explanation

To solve the question about the net force acting on a particle of a rigid body that is rotating with a constant angular speed about a fixed vertical axis, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the System**:
We have a rigid body rotating about a fixed vertical axis with a constant angular speed (ω). A particle (let's call it P) is located at a distance (r) from the axis of rotation.

2. **Identifying the Motion of the Particle**:
