Explanation:

mgsin37

0

=10×10×3/5=60N

f

l

=μ=0.2mgcos37

0

=0.2×10×10×4/5

=16N

Friction force alone is unable to balance mgsin37

0

. Hence, F is required for balancing. Here two cases arise.

Case I:

If the block has tendency to slide down, friction on block will act upwards.

F + 16 = 60

RightarrowF=44N

This is the minimum force required for balancing.

Case II: If the block has on tendency to slide up, friction on block will act downwards.

F = 60 + 16⇒ F= 76 N

This is the maximum force required for balancing.

Therefore, for balancing 44N≤F≤16N
