Answer 1

In the arrangement shown in figure

m

$ma = mb = \: 2kg$

. String is massless and pulley is frictionless. Block B is resting on a smooth horizontal surface, while friction coefficient between blocks A and B is

$meu = 0.5$

. What maximum horizontal force F can be applied so that block A does not slip over the block B?

$g = 10m \div {s}^{2}$
