Homework Answers
If there is enough force to cause sliding on all interfaces, (we
will check that there is) the tension in the rope will equal the
friction force attempting to move the smaller block away from the
wall
the normal force of the lower block on the upper block is the
weight of the upper block
The friction force between the two blocks is the coefficient of
friction times the normal force.
T = Ff = μmg = 0.2*5*9.8= 9.8 N
to check that there is enough force to cause motion between all
touching surfaces, we add the tension force to the friction force
with the ground and expect it to be less than the applied
force
F =0.8 + 0.2(5 + 10)(9.8) = 39.2 N
as this is less than the applied force of 50 N, the Tension value
is valid.
therefore answer is B)

supposed to get? Please explain!
