Text Solution

AI Generated Solution

To determine the torque exerted by the gravitational force of the Sun on the Earth, we can follow these steps: ### Step 1: Understand Torque Torque (\( \tau \)) is defined as the product of the force (\( F \)) applied and the distance (\( r \)) from the point of rotation (or axis of rotation) to the line of action of the force, multiplied by the sine of the angle (\( \theta \)) between the force vector and the position vector: \[ \tau = r \cdot F \cdot \sin(\theta) \] ...
