Q 4 **Question 4**A mass \( m \) sits at a distance \( r \) from the center of a rough platter rotating with angular speed \( \omega \). Which of the following would result in increasing the maximum rotational velocity (\( v_{\text{max}} = \omega_{\text{max}} \times \text{radius} \)) at which the platter can rotate without the mass slipping?- Increasing the mass itself- Decreasing the mass- Increasing the coefficient of static friction- Decreasing the coefficient of static friction- Two of the above- NOTA**Question 5**In the previous problem, suppose the radial distance from the center of the platter to the location of the mass is increased. Which statement below is true?- The value of \( v_{\text{max}} \) would be increased- The value of \( v_{\text{max}} \) would be decreased- The static frictional force on the mass would increase (assuming \( \omega \) is unchanged)- The static frictional force on the mass would decrease (assuming \( \omega \) is unchanged)- Two of the above are true- NOTA**Question 6**A car (purple circle) is moving on a banked track; the graphical addition of forces acting on the car is shown in the accompanying figure. From the figure, which is true of the force of friction?*(Note: No graph or diagram is provided in the image for further explanation.)*
