Three masses m, 2m and 3m are placed on a horizontal surface. A forceFis shown acting on m3. Assuming μs,k is the same between all of the masses and the horizontal surface, answer the following:

a) Find the expression for the net force on the 2m mass.

b) ForFconstant, μs,k =0 then the answer to (a) must decrease. Prove or Disprove.

2. Relevant equations

F=ma

3. The attempt at a solution

F=ma

μs,k =m+2m+3m
