A) "$\mu$_B $\mu$_A" B) "$\mu$_A $\mu$_B" C) "$\mu$_B = 2 $\mu$_A" D) "$\mu$_A = 2 $\mu$_B"

Question

Two objects, A and B, are placed on an inclined plane that can be rotated to different angles of elevation. A starts to slide at twice the angle of elevation that B starts sliding. The respective coefficients for static friction for A and B are $\mu$_A and $\mu$_B. Choose the last answer that is correct. A) "$\mu$_B > $\mu$_A" B) "$\mu$_A > $\mu$_B" C) "$\mu$_B = 2 $\mu$_A" D) "$\mu$_A = 2 $\mu$_B"

Quizplus · Accepted Answer

The static friction coefficient is related to the angle at which an object starts to slide. Since A starts sliding at twice the angle of B, it means A has a higher static friction coefficient than B.
