Two identical blocks rest on identical horizontal tables. For block A, the coefficient of static friction is μs,A=0.60. For block B it is μs,B=0.30. No other forces act horizontally. Which statement correctly compares the graphs of static friction magnitude Ff,s versus applied horizontal force Fapp for the two blocks?
a) Block A’s graph has a steeper initial slope than block B’s because μs,A is larger.
b) Neither graph shows a region of slope 1; both begin flat until Fapp equals μsFn.
c) Both graphs start as lines of slope 1, but block A’s graph reaches its maximum at a larger Fapp than block B’s.
d) Block B’s graph reaches a larger maximum static friction because its μs value produces less slip.
