Question

(6. A block of mass 5 kg rests on a table. 8 N horizontal force is applied
to push the block. Find out the force of friction between the block
and the table. Given. H, = 0.3 and =0.2, between the block and
the table and g = 10 ms?​

Answer 1

Just move,

→ static friction will apply

fs=10N=μ3N

⇒μs=5010=0.2

After start of motion

kinetic friction will apply

fk=8N=μkN

μk=508=0.175
