Question

problem 7 (1 point) Two objects of equal masses mA me-1kg are placed on a horizontal rotating disk; their distances from the center are RA - 1 m and Re 4m. The objects are made of different materials, and the coefficients of static friction between the objects and the disk are μ^ and The disk is very slowly increasing the angular speed, so that the angular acceleration is negligible. Both objects start sliding off the disk at the same time once the disk reaches the angular speed cuax, which one of the following statements is true? OA (N) None of the above.

Answer 1

Concept: here, the friction force provides the centripetal force and when centripetal force required exceeds the maximum friction force that can be applied, objects slide,
