How to Prevent Your Eraser from Sliding Off a Clipboard

What is the minimum coefficient of static friction needed to prevent an eraser from sliding off a tilted clipboard at 23°?

A. 0.42

B. 0.16

C. Not enough information to tell

D. 0.26

Answer:

The correct answer is C. Not enough information to tell.

To prevent your eraser from sliding off a tilted clipboard at an angle of 23°, you need a minimum coefficient of static friction. In this case, the minimum coefficient of static friction needed cannot be accurately calculated with the given data provided. Therefore, the correct answer is C. Not enough information to tell.

Remember to always ensure the stability of your eraser on a tilted surface to avoid any mishaps!
