Answer 1

Answer #1

here,

for A typical pulley with no incline

when the mass of block is changed , the normal force changes

frictional force , ff = u * N

so, the frictional force is changed

the coefficient of friction does not depends upon the mass , it depends on the nature of the surface between them

when the mass of hanger changed

the friction force remains the same
