Q. A block of mass $1 k g$ lies on a horizontal surface in a truck. The coefficient of static friction between the block and the surface is $0.6$ if the acceleration of the truck is $5 m / s^{2}$ the frictional force (in $N$ ) acting on the block is ?

$F_{external} = 5 N$
$f_{r} = μ m g$
$= .6 \times 1 \times 10 = 6$
$F_{external} < f_{r} (mass)$
$f_{r} = 5 N$
