Question

What can be inferred regarding the limiting frictional force in the following four figures

1. Fa=Fb=FC=FD
2.Fa<Fb<Fc<Fd
3.Fa>Fb>Fc>Fd
4.Fa=Fb<Fc<Fd

please help me as soon as possible

Answer 1

Answer: answer is a)

Explanation: when on a body the force is same than there friction is also same and equal

Answer 2

Answer:

option A

Explanation: as friction  is independent of area , force on all bodies is same,

then force of friction is equal in each case
