Problem

In a laboratory, pairs of values of limiting friction

F_{\text{lim}}

and normal reaction

N

for a wooden block on a table are plotted. The best-fit straight line passes through the origin and has a slope of

0.35

. This slope numerically represents a)

\sin

of the angle of repose for the block–table pair b) coefficient of kinetic friction between block and table c) coefficient of static friction between block and table d) reciprocal of the coefficient of static friction between block and table
