Motion of the rigid body is observed from an inertial frame of reference. Rigid body is rotating with nonuniform 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 problem regarding the net force acting on a particle of a rigid body that is rotating with a non-uniform angular speed about a fixed vertical axis, we can break down the solution into clear steps.

### Step-by-Step Solution:

1. **Understanding the System**:
- We have a rigid body rotating about a fixed vertical axis with a non-uniform angular speed (ω). This means that the angular speed is changing over time.

2. **Identifying the Particle**:
